Temperature measurement HADControl

1. Introduction

The HADControl general purpose board provides access to many external interfaces and devices.
The task is to replace the already running ansatz of the HADES MDC Gas Monitor temperature measurement by a pure EPICS based design.

1.1. Components

1.1.1. HADControl (aka HADSHOPOMO)

• General Purpose IO Module for SlowControl and small DAQ-systems
• developed at EE department of GSI
• Contact: Michael Traxler

1.1.2. HADSHOPOMO for distributed temperature measurement

• Readout of temperatures from sensors on a 1-Wire^© bus via HADControl (aka HADSHOPOMO)
• GSI summer student program 2006: Giacomo Ortana, Italy
• Supervisor: Michael Traxler
• Documentation:
  • Wiki - page
  • Report: Implementation of a new system for measure the temperature of the MDCs in the HADES experiment: the system is based on the 1-Wire^© protocol provided by Dallas Semiconductors., (local copy)

• Contact/Design: Peter Zumbruch
• Project Page

7. Outlook

Since there is a general purpose HADCon(trol) API including 1-wire measurements being developed, ... see project page, the inner access routines to the HadCon have to be redefined and rewritten.
