TURBO: VFAT CTRL/READOUT BOARD

INVOLVED PEOPLE

TOTEM(Pisa/Siena group and students) , GDD-RD51(Matteo, Gabriele) , CMS GEM upgrade group (Andrey, Stefano, Michal, Nicholas, Tommy, students…), TERA(Sarolta, Nail) and all the people that I’ve forgotten….

Starting Point: TOTEM TTP (Paschalis, Walter, Paul)

Main Idea: - Portable .- User friendly (?).

- With a “real time” response for the understanding on what is going on .- With the capability of DAQ for small/medium size system.- Fast (ref. VFAT 100kHz, not yet optimized to the maximum achievable).

TURBO is a stand alone portable Control and Data Acquisition platform for the VFAT front end ASIC. It has been developed on the basis of the Totem Test Platform (TTP) used for testing the TOTEM hybrids equipped with VFAT chips. Each TURBO board can be interfaced with 8 VFATs. “In Parallel” (available) and “In daisy chain” (under development) set up configurations allow to work with more than 8 chips.TURBO is controlled by a PC running LabView via USB interface (Quick-USB). The number of USB ports needed is equal to the number of TURBO boards used in the “In Parallel” set up configuration. In the Daisy Chain operation instead, a single USB port is needed for each group of 8 TURBOs. LabView softwares have been developed for VFATs control, standard calibration scans (threshold, calibration pulse, latency ), Data Acquisition and Quality Monitoring. 3

XML VFAT Interface (a useful upgrade)All the VFAT registers can be Loaded from or Saved to XML files…

…that can be opened/written with std editor or excel

Easy config/check

THRESHOLD SCAN

Performed for all the channels

You can view all of them using the “vfat channel” control.

You can save (*) the scan channel by channel in ASCII format and analyze/compare with other scans easily with any software.

(*) with the CTRL labview software we never save the VFAT Raw Data, but the scan output directly. For Raw Data you have to use the DAQ labview software.17

CALIBRATION PULSE (and Internal Latency Scan)After having found the internal right latency,,,,

… a calibration scan can be performed

You can save the scan channel by channel as for the threshold scan in ASCII format and analyze/compare with other scans easily with any software.

CALIBRATION PULSE: something that we have to doFrom single channel measurement…

… to multi-channels analysis

S-Curve

S-Curve Mean

S-Curve Sigma

At the moment you have to do the scan and save the data channel by channel (not totally true: it depends on the number of channels that we can pulse at the same time).

We have to implement an automatic procedure to scan all the channels that we have.

19

Beam Latency Scan Counts per trigger vs latencyNeeded to take data properly, but… … it could provide also some timing information

A fastest (signal that starts at higher latency) with MicroMegas

Information about the signal time structure can be collected playing with the VFAT monostable polarity …

S-Bit Settings(which vfats, which sector..)

Trigger Counter and Timestamps

Timing: Sbit provided to the Andrey’s TDC

LV1 Induced Noise seen with the SBit

Timestamps (reset every SPS spill). Nice: Different rate between the beginning and the end of the spill has been observed and also some beam adjusting, optimization,…

They can be used as a synchronization check with other DAQs(saved in the raw data)

List of XML files for the VFAT settings
