HADES Magnet: Hall Sensor Readout

Introduction

Using the port folio of HadCon based applications the objective of this project is to realize a reading of several hall sensor values to be available inside HADES EPICS based control system.

The major components are:

• (HADES Magnet)
• Hall sensor(s)
  • Manual_F779.02.02-1.8.pdf: Manual of the Hall-Sensors
• sensor line(s)
• 1-wire 16-bit Quad ADC(s) DS2450 (data sheet)
  • The 1-wire ADCs are placed on a small separate PCB:
    • OWADC1:
      • Schematics of OWADC1
• HadCon
• HadCon API
• already existing EPICS database templates (already used by RPC Low Voltage controls)
• HADES HadCon startup script environment

Notes:

• For this application 2 sensors are planned which feed separate 1-wire buses.
