  1. NA62 scintillator test system

  2. Scintillator test system Assumption: • Stepper motor controlling position of source/photo tube • Test DAQ taking pulses to verify uniformity • Stepper control linked to DAQ • DAQ VME/Linux/gcc based • Interface to CAMAC • LabView ? To be discussed: Protocol stepper <-> DAQ (USB(???), serial, h/w, ?) Timeline CAMAC interface LabView drivers ?

  3. Test system electronics list • Stepper control • Some NIM modules • VME system • CAMAC system Known to be available • VME: • Crate • controller w. h/disk (on loan) • SLC4 + CERN drivers installed • a few VME modules (TDC, scaler, ADC?????) Known to be missing • Power cable for VME crate • CAMAC interface • 2nd CAMAC crate for commissioning • 2nd VME contoller need to share R.D. / NA62

  4. CAMAC controller • 6U VME, reduced depth (cost) • Bus drivers, CPLD • Module might be physically extended to standard depth, including front panel (K.G.) • CAMAC module populating 2 slots (standard /control) • Bus drivers, CPLD • Use modified totem pole drivers rather than open collector • Linked by 50-pin flat cable

  5. CAMAC controller: some details • VME side (almost) ready for production • Using ABT bus drivers (48mA), fully compliant with VME specs • Bus controller is XC95XL programmable chip needs firmware to be written ! • CAMAC side will populate 2 slots. Try and cannibalize old CAMAC controller to get hold of half the stuff • The other half is the programmable one • Use CPLD again, write firmware ! • Avoid open collector drivers, which are not readily available on the market any more • Use ABT245 totem pole / tri-state drivers and protect by series resistors • Provide for Schottky diodes to improve pulldown impedance

  6. Some remaining issues CAMAC/VME side lead time 8 working days CAMAC/CAMAC side ? Reinhold rather busy with student lab equipment Protocol stepper <-> DAQ LabViewdrivers
