Electronics Periphery

HV Power Supply

  • Need 7 channels per module or voltage divider
  • Up to 4 kV
  • Trip control
  • Current monitoring ~50pA

Gas-Flow and -Quality Control

  • Flowmeter
  • Moisture and oxygen sensors

Current Control

  • Measure leakage current with a pico

amperemeter

Electronics Periphery

  • Accurate distance

measurement

  • ~ 1.8 x 0.8 m2
  • Quality control of

stretching Profile Laser

APV25 – Problems

  • Waveforms -> Nice for R&D
  • Not capable of required rates
  • Highest rate achieved ~7 kHz
  • We need O(MHz)
  • > new frontend chip VMM

SRS - Configuration

14

  • Scalable Detector Control
  • Developed at NTUA

SRS SDC

  • Set baseline
  • Set gain
  • Set latency

APV

  • Set active APVs
  • Set trigger mode

FEC

  • Include to our slow control

DAQ – mmdaq2

  • Developed for

Micromegas

  • Based on root
  • Load pedestals for

APVs

  • Monitor analog

input

  • Nice online statistics

Working Setup

  • We have a fully working DAQ
  • Now:
  • Write own slow control
  • Set up own DAQ
  • Get hands on VMMs
