Institute for High Energy Physics Protvino Moscow region, Russia
Content: Content 1. Tuning of RPC performance
2. RPC design for DHCAL
3. RO electronic activity
4. R&D plans
Tuning of RPC performance: Tuning of RPC performance Use glass for anode and cathode
( standard RPC)
Decrease the charge in the gas gap
Consequences:
Possibility to diminish ageing effects
Possibility to increase maximal rate
Joint adjustment of RPC and RO electronics Decision
Tuning of RPC performance: Tuning of RPC performance
Tuning of RPC performance: Tuning of RPC performance
Tuning of RPC performance: Tuning of RPC performance - It seems that tuning should be done around
basic TFE/ISO mixture
It is intended to study (10-100) pC region
withh possibility to work at 50 mV threshold
RPC design for DHCAL: RPC design for DHCAL
RPC design for DHCAL: RPC design for DHCAL
RPC design for DHCAL: RPC design for DHCAL Dead zones
RO electronic activity: RO electronic activity General scheme
for 64 channel read out Two parts:
Conditioning (analog)
FPGA (digital)
RO electronic activity: RO electronic activity Steps for design and usage Approaches for conditioning Comparators - Protvino
Trans impedance amplifiers (TIAs) - Minsk
RO electronic activity: RO electronic activity Conditioning - comparators
RO electronic activity: RO electronic activity Conditioning - comparators
RO electronic activity: RO electronic activity Conditioning - TIAs
RO electronic activity: RO electronic activity Conditioning - TIAs
R&D plans: R&D plans design and tests of approach-0 for RO electronics (step 1) Dec02
tuning of RPC performance to Dec02 decrease the gap charge
design of a small RPC plane Dec02
construction of this plane with a few hundred RO channels (step 1) Mar03
beam tests of this plane in IHEP Apr03
