Introduction 1.1

0 The introduction of a new family of high-performance cryogenic probes representsa major step forward in NMR instrumentation.

Developed in order to cover a huge number of chemistry applications, the Cryo-Probes offer outstanding performance with respect to signal-to-noise and mea-surement time.

This manual covers:

• Installation of the rf wiring for different types of CryoProbes

• Software description

• Technical data

• Some service informations

Most of the information given in the ‘HPPR Technical Manual‘ (Z31075) and ‘HPPR/2 Technical Manual’ (Z31559) remains valid for the HPPR CRP MOD-ULEs.

Features 1.2

0 • Practical and easy-to-use.

• Integrated cryocooled preamplifiers, filters and t/r-switches make maximumuse of the significant signal-to-noise improvement in a cryogenic cooled signaldetection system.

• Additional functionality is offered in conjunction with the HPPR CRP ASSEM-BLY as for example:- Computer controlled signal routing between the CryoProbe and the HPPR CRP MODULEs respectively HPPR/2 MODULEs

- Improved spectral purity of the rf pulses by using the built-in filters of theHPPR CRP MODULEs (HPPR/2 MODULEs)

- Probe tuning of all nuclei- PICS (Probe Identification System)

RF Wiring for a Conventional Probe (HPPR CRP) 1.8

0 As mentioned earlier, a HPPR CRP ASSEMBLY may be used with a conventionalprobe.

However, some precautions have to be taken into consideration.

• The HPPR 1H CRP MODULE may be used without change.

• The HPPR 2H CRP MODULE may be used without change.

For X-nucleus the choice of module depends on the nuclei and the RF power youintend to use.

• For all other nuclei than 13C or 15N use the HPPR X-BB19F 2HS MODULEyou possibly already have (if you have a BLAX 500 transmitter, please makesure that your HPPR X-BB MODULE is able to handle the 500 W).Connect the RF cables coming from or leading to the HPPR X-BB19F 2HSMODULE at the SELECTOR manually and pull the ribbon cable connectors atthe JUNCTION BOARD of the HPPR 13C CRP MODULE and HPPR 15NCRP MODULE!

• For 13C or 15N nucleus you may use the HPPR 13C CRP orHPPR 15N CRP MODULE provided that you intend to use NOT MORE THAN300 W RF power!

NOTE:

1. For the XWIN-NMR configuration, please consult the section "XWIN-NMR se-lection of observe and decoupling nuclei (HPPR CRP only)" on page 16 inthe chapter "Operation".

General Description

RF Wiring in case of existing standard HPPR MODULEs 1.9

0 The standard HPPR CRP ASSEMBLY may be combined with already existingHPPR MODULEs. Up to five HPPR MODULEs can be powered at the same time(AVANCE spectrometers only!). Depending on whether you use the HPPR CRPMODULEs or an additional HPPR MODULE some manual signal routing has tobe done at the HPPR SELECTOR/TUNING-SPLITTER as described later on.

For information about the HPPR/2 MODULE family, please consult the ‘HPPR/2Technical Manual’ (Z31559).

Combination with a HPPR 19F or a 3H MODULE 1.9.1

Installation:

• Power the HPPR 19F or 3H MODULE by the ribbon cables leading from theHPPR CRP COVER MODULE to every single HPPR MODULE.

• Connect the rf cables of HPPR 19F or 3H MODULE to the 19F-connectors ofthe HPPR SELECTOR/TUNING-SPLITTER.

Combination with a HPPR X-BB31P 2HS MODULE 1.9.2

In case of an already existing HPPR X-BB31P 2HS MODULE the deliveredHPPR X-BB19F 2HS MODULE may be used instead.

Note: If you have a BLAX 500 transmitter, please make sure that your HPPR X-BB MODULE is able to handle the 500 W. A HPPR X-BB19F 2HS MODULE de-livered with the HPPR CRP ASSEMBLY is able to handle the 500W.

Combination with a HPPR X-BB19F 2HP MODULE 1.9.3

In case of an already existing HPPR X-BB19F 2HP MODULE the deliveredHPPR X-BB19F 2HS MODULE may be used instead.

Installation:

• Power the HPHP 19F/1H/3H and X-BB HP MODULE by the ribbon cablesleading from the HPPR CRP COVER MODULE to every single HPPR MOD-ULE.


RF Wiring in case of existing standard HPPR MODULEs

• Connect the rf cables of HPHP 19F/1H/3H MODULE to the 19F-connectors ofthe HPPR SELECTOR/TUNING-SPLITTER.

• Connect the rf cables of HPHP X-BB MODULE to the UB-connectors of theHPPR SELECTOR/TUNING-SPLITTER.


General Description


Operation 22000000

CryoProbe Operation with HPPR/2 ASSEMBLY 2.1

0 The later released HPPR/2 family supports a connected CryoProbe with morecomfort (needs XWINNMR 3.1 or later). There is no additional software neces-sary.

Observe with convential probes

No special commands are necessary.

Observe with the CryoProbe

CryoProbe operation has to be forced by the UniTool as follows:

• xwinnmr -e UniTool hppr

• [P]reamplifier module

• [5] 1H, [7] 2H or [8] 13C

• [S]et Force-State

• [0] off, [4] cold

• [Q], [Q], ...

After forcing to CryoProbe operation all following commands issued by XWIN-NMR concerning the HPPR/2 (inclusive ‘wobbling’) are interpreted in order toroute all signals to and from the CryoProbe.

Bypass the CryoProbe for debugging purpose

The internal CryoProbe preamplifier may be bypassed for debugging purpose asfollows:

• xwinnmr -e UniTool hppr

• [P]reamplifier module

• [5] 1H, [7] 2H or [8] 13C

• [S]et Force-State

• [0] off, [4] cold, [8] bypass

• [Q], [Q], ...


Operation

CryoProbe Operation with HPPR CRP ASSEMBLY 2.2

0 The BRUKER CryoProbes are supported by a modified preamplifier assembly.The HPPR CRP ASSEMBLY (i.e. Z003422) includes a HPPR CRP COVERMODULE which has an additional RF signal selector controlled by software as de-scribed in the following sections.

HPPR CRP Installation Software for XWIN-NMR 2.2.1

Installation of the AU programs ‘crpon‘, ‘crpoff‘, ‘crp2hon‘,‘crp1hxon‘ and ‘crpwobb‘

If the ‘crpon‘, ‘crpoff‘, ‘crp2hon‘, ‘crp1hxon‘ and ‘crpwobb‘ commands donot exist on your workstation, an add-on package is available from the BRUKERftp server (ftp.bruker.de) called:

crponoff.tar.gz

(/pub/nmr/xwinnmr/utilities/crponoff.tar.gz)

After unzipping and untaring of the package the crponoff.readme file gives astep by step installation guide.

Note: The original crponoff.tar file should be removed.

The new commands must be compiled in XWIN-NMR with xau <newcommand>,i.e. xau crpon.

Configuration of the HPPR CRP ASSEMBLY

The configuration of an AVANCE spectrometer with HPPR CRP ASSEMBLY fol-lows the same rules as for a standard HPPR. The only requirement is a ‘cf‘ config-uration of the spectrometer.

The file uxnmr.info should look similar to:

.....

Preamplifiers:- HPPR preamplifier 1 connected to DRX500:/dev/tty01module 1: 2H Modulemodule 2: X-BB31P_2HS Modulemodule 3: 1H Modulemodule 4: X-BB19F_2HS Module

Note: For the RF wiring of a HPPR CRP ASSEMBLY with a CryoProbe or a con-ventional probe, please consult the chapter "General Description" on page 5.

Note: Whenever you do a manual reconfiguration at the HPPR CRP ASSEMBLY(pulling or connecting the ribbon cable connectors at the JUNCTION BOARD),please do it under power-off condition and make a ‘cf‘ afterwards!

XWIN-NMR selection of observe and decoupling nuclei (HPPR CRP only) 2.2.2

The observing nucleus can be selected in XWIN-NMR by the command ‚edasp’and by selecting the corresponding F1 nucleus. The decoupling nuclei should be


CryoProbe Operation with HPPR CRP ASSEMBLY

selected in F2 or/and F3. The routing for the RF should be selected manually likethe following example:

Figure 2.1. ‘edasp‘ routing example for a TXI CryoProbe

For each observable channel, a corresponding HPPR MODULE is required. Theselective HPPR MODULEs can be routed automatically. For X nuclei, the HPPRXBB19F or HPPR XBB31P module must be routed manually.

HPPR CRP COVER RF selection control 2.2.3

The XWIN-NMR command ‘edasp‘ isn’t aware of the existence of a CryoProbe.Therefore, the correct RF path for the observe and the lock signal has to be se-lected by certain AU programs called ‘crpon‘, ‘crpoff‘, ‘crp2hon‘, ‘crp1hxon‘and ‘crpwobb‘. These commands control the routing in theHPPR CRP COVER MODULE. Without a HPPR CRP COVER MODULE, the AUcommands will hang on and must be killed manually.

Note: The selection for the observe channel is always coupled with the lock chan-nel. ‘crpon’ means: both, the observe and the lock signal come from the Cryo-Probe. During switching the lock signal may be temporarily lost. The usual lockgain and phase adjusting has to be done after that.

Observe with conventional probes

Conventional probes as e.g. a TXI can be used with the same HPPR CRP AS-SEMBLY provided that NOT MORE THAN 300 W is used for the HPPR 13C CRPor HPPR 15N CRP MODULE. Otherwise you have to check whether your possi-ble already existing HPPR XBB19F 2HS MODULE is able to handle 400 to 500W.

HPPR 13C CRP MODULE

HPPR 15N CRP MODULE


Operation

By calling up the ‘crpoff‘ command the signals of the HPPR MODULEs are rout-ed in the HPPR CRP COVER MODULE to the observe and lock receivers.

Note: For the RF wiring of a HPPR CRP ASSEMBLY with a conventional probe,please consult the section "RF Wiring for a Conventional Probe (HPPR CRP)"on page 11 in the chapter "General Description".

Note: For reinstallations from CryoProbe operation to conventional probes, pleaseswitch off the power supply at the AQR chassis and make a ‘cf‘ afterwards!

Note: Default state after a power-up / reset is ‘crpoff’.

Observe with the CryoProbe• ‘crpon‘

- The signals of the built-in cooled preamplifiers are routed in the HPPR CRP COVER MODULE to the observe and lock receivers.

• ‘crp2hon‘- measurement of passive channels (without built-in cooled preamplifiers),e.g. 13C or 15N depending on your type of CryoProbe.

• ‘crp1hxon‘(for debugging only)

Wobble of a CryoProbeA CryoProbe must be tuned and matched via the transmit channel of the corre-sponding HPPR CRP MODULE. The following commands are available:

• ‘crpwobb‘- wobbling of all channels, no lock signal of the CryoProbe

• ‘crp2hon‘- wobbling of observe channels (e.g. 1H, 13C, 15N), 2H lock operation.

Note: After tuning and matching of a CryoProbe, the RF path routing must be re-set by the ‘crpon‘ command.

Service Information 55000000

General 5.1

0 The CryoProbe is designed for high reliability and has been tested thoroughly dur-ing the manufacturing process. However, a few things are valuable to know incase of trouble. Every CryoProbe is a very complex unit with electronics workingat cryogenic temperature and helium leakproof vacuum technology. The specialrequirements for repair and successful reassembly of a CryoProbe are unlikely tobe met outside of a BRUKER manufacturing facility. Irreversible damage to theprobe will result, if inproper techniques and tools are used.

Therefore, the CryoProbe MUST NOT BE OPENED! Any warranty will be invalid ifan attempt is made to open the CryoProbe by a non-approved repair facility! Con-tact a BRUKER representative in case of problems.

Furthermore, it is advisable to perform a few checks before calling BRUKER ser-vice in order to make sure whether the CryoProbe is causing the trouble or some-thing else.

Basic System Checks 5.2

0 The following hints and the block diagram should assist you in your enquiries.

• Check all connectors: Are they at the right place? Especially, is the POWERcable to the CRYOPROBE properly connected at the back of the HPPR CRPCOVER?

• Does the spectrometer work satisfyingly with a conventional probe? Check inparticular those functions and measurements which seem not to work properlywith the CryoProbe, if possible.

• Check the PROBE TUNING function (‘wobble‘) for all selectable channels: Doyou get a tuneable dip on your display? (This check indicates if most of the sig-nal routing to and from the CryoProbe and most of the CryoProbe itself isworking)Note: A CryoProbe must be cooled down to its operating temperature for tun-ing and matching. Do not try to tune a CryoProbe when warm!

• Try to reproduce a standard spectrum you successfully recorded not long agowith the same standard sample and identical experimental parameters.

For further tests you need measurement instruments like e.g. a 500 MHz oscillo-scope.

• Set the spectrometer into the PROBE TUNING mode (‘wobble’) (in the TUN-ING mode you get a traceable sweeped signal). With help of the oscilloscope,the following block diagram and a HPPR Technical Manual you can trace thetuning rf signal and all necessary trigger pulses at the HPPR and CryoProbeinterface connectors.
