Project: POLAND - Profile Acquisition digitizer

former project name: PGProto - Profile Grid Prototype


GSI Beam Diagnostics department together with Experimental Electronics department has started in 2008 investigations on a new economical solution for Profile-Grid electronics. The old front-end amplifiers and control devices of the existing readout devices are outdated and very expensive.

After extensive and promising tests with a 4-channel QFW (Charge-Frequency-Converter) test board (see references Four Channel QFW Module datasheet), it was decided to develop under the project name PGproto a 32 channel prototype system with 8 QFW-ASICs. The goal of the project was to perform a functional test of ASICs connected to a SEM-Grid (Secondary Electron eMission Grid) under real beam conditions at GSI.

End of 2012 there was the next step to the final electronic version: the development of the final design of PCB, mainboard and controler PCBs. There were assembled in 2013 and also the first tests started in this year. The final project name was also fixed in 2013 to now: POLAND.


coming soon...
