New shashlyk prototype status

  • The first version of the mold was ready by the end of

January, but after some tests the manufacturer decided to rebuild one part

  • New mold should be assembled and checked in 2 weeks
  • New die to produce lead plates – also in 2 weeks
  • Modified HV base (type B) is developed and tested – non-

linearity of a few percent with 100 mA output

  • All the materials to produce 4-5 modules of FSC (lead,

polystyrene and dopants, Y11 optical fiber) are available

  • The plan to produce prototype modules in April-May.

Pile-up recovery studies for FSC

  • FSC signal is shorter in comparison with target EMC EC
  • Deconvolution algorithm is different
  • First simulation showed the possibility of pile-up

recovery within a range of up to 30 ns Simulated overlaped signals from FSC and simulation results of digital pile-up recovery

Slow control node for FSC

  • First version based on uC STM32F2xx is ready
  • Functionality includes HV control (Cocroft-Walton type

bases) and 1-wire protocol to read temperature sensors

  • Iterface: Modbus on RS485, CAN bus available, but

currently not implemented

  • Compatibility with slow control system developed in

Bohum should be discussed

Possible preassembly at Julich

  • Prototype after tests at Mainz (may be used in 2014, first

half of 2015)

  • Full readout chain including PMT and HV base, cable and

ADC
