Multichannel readout electronics for MPGD
based on different types of IDEAS chips.
Nail Malakhov.David Watts.
IDEAS chips Self triggering : VATAGP5 (triggers and analog readout) : • 128 channels. 40 nsec fast shaper and 250
nsec low shaper.• up to 10 MHz readout clock • Serial readout (128 channels : 12.8
mksec/event)• Sparse readout ( few triggered channels :
less 1 mksec)
VA64TAP_(few different version with different gain and dynamic region): • ONLY triggers (each channel independent) -
64 triggers output
• 64 channel. Peaking time = 50 nsec.• 2fC treshold (theoretical) and 10 fC
(practical).• 2.5 Mhz uniform rate (for signal above 70 fC)
