DESPEC: Implantation DSSD Concept
• Super FRS Low Energy Branch (LEB)• Exotic nuclei – energies ~50-150MeV/u• Implanted into multi-plane, highly segmented DSSD array• Implant - decay correlations• Multi-GeV DSSD implantation events• Observe subsequent p, 2p, , , , p, n … decays• Measure half lives, branching ratios, decay energies …

Implantation DSSD Configurations
Two configurations proposed:
a) 8cm x 24cm “cocktail” mode many isotopes measured simultaneously
b) 8cm x 8cm high efficiency mode concentrate on particular isotope(s)
![Page 4: Advanced Implantation Detector Array (AIDA): Update & Issues presented by Tom Davinson on behalf of the DESPEC-DSSD/AIDA collaboration Tom Davinson School.](https://reader035.fdocuments.in/reader035/viewer/2022070307/551ae1e05503466b6a8b5c4b/html5/thumbnails/4.jpg)
DSSD Segmentation
We need to implant at high rates and to observe implant – decay correlationsfor decays with long half lives.
DSSD segmentation ensures average time between implants for given x,yquasi-pixel >> decay half life to be observed.
• Implantation profilex ~ y ~ 2cmz ~ 1mm
• Implantation rate (8cm x 24cm) ~ 10kHz, ~kHz per isotope (say)• Longest half life to be observed ~ seconds
Implies quasi-pixel dimensions ~ 0.5mm x 0.5mm
Segmentation also has instrumentation performance benefits

DSSD
Technology well established(e.g. GLAST LAT tracker)
• 6” wafer technology 10cm x 10cm area
• 1mm wafer thickness
• Integrated components a.c. coupling polysilicon bias resistors … important for ASICs
• Series strip bonding8.95 cm square Hamamatsu-Photonics SSD before cutting from the 6-inch wafer. The thickness is 400 microns, and the strip pitch is 228 microns.

AIDA: Instrumentation Requirements
Large number of channels required, limited available space and cost mandateuse of Application Specific Integrated Circuit (ASIC) technology.
Requirements
• Selectable gain: low 20GeV FSR (use reset) :
intermediate 1GeV FSR :
high 20MeV FSR• Noise ~ 5keV rms.• Selectable threshold: minimum ~ 25keV @ high gain ( assume 5 )• Integral and differential non-linearity• Autonomous overload recovery ~s• Signal processing time <10s (decay-decay correlations)• Receive timestamp data• Timing trigger for coincidences with other detector systems
DSSD segmentation reduces input loading of preamplifier and enablesexcellent noise performance.
