It is a good idea to share early experience with hardware between the DCS detector subgroups, as this would encourage early standardization and pooling of knowledge. Please sign your posts.

If you have researched, tested, prototyped or purchased sensing/control hardware for your detector group, or you have previous experience with a certain piece of hardware and plan to use it, please add a short description herein. Of most relevance are the connectivity, driver availability and technical support available within PANDA. Please link to here from

PT100 (EMC)

The self-made PT100 for the EMC are based on a 50 cm long platinum wire with a diameter of 25 µm. The platinum wire is brought onto a self-adhesive Kapton film and covered with a non-adhesive film on the back-side. The measurement is to take place via a four-terminal sensing, which allows to ignore the resistance of the supply wires to the point where the sensor starts. This is a common method to ensure high-precision resistance measurements. The resistance of the sensor at 0 °C is chosen to be 100 Ohms to provide comparability to commercial PT100-sensors and to obtain measureable voltages with a testing current of only 1 mA. For read-out the THMP will be used. -- FlorianFeldbauer - 25 Sep 2009

Humidity Sensors (EMC)

For the humidity measurement inside the EMC the sensors HIH4000-003 from Honeywell are used. For read-out the THMP will be used. -- FlorianFeldbauer - 25 Sep 2009

Pressure sensors

  • Commercial sensors, type MPXAZ4115A6U from Semiconductor Technologies, measure the relative pressure inside the EMC within a range from 15 to 115 kPa. The output voltage is between 0.2 and 4.8 V DC, and the supply voltage is 5 V. Here again, the reading out is carried out by the THMP. -- PatrickFriedel - 17 Jan 2013. datasheet
  • Swagelok Pressure Transducers S Model with milliampere output signal are used for measuring the pressure inside the cooling pipes for the luminosity detector. Read out via THMP. -- FlorianFeldbauer - 01 Feb 2013. link

Production of extremely thin sensor cables (EMC)

The very thin cables (90 µm thick) are mainly used for the self-made thin PT100 temperature sensors, but they can also be utilized for the humidity and pressure sensors. They are made from a two-layer copper/polyimide foil, type Pyralux AC182500R from DuPont. An exposure mask is used for the copper layer. The layout of the mask for the temperature sensor cables is to be found at: ExpMask_TempCable.png Please refer to ExpMask_HumExtCable.png for the layout of the humidity sensor cables and the extension cable. The layouts are printed twice on DIN-A3 transparent foils, and by putting the foils above each other, an adequately dark exposure mask is obtained. Then the non-exposed areas are etched off and single cables are cut out and covered with self-adhesive Kapton foil. -- PatrickFriedel - 17 Jan 2013

Light Pulser (EMC)

Irradiation Tests of Electronic Components

Target CompactRIO controller

For the target subsystem, we will use a CompactRIO controller running LabVIEW, which will communicate with the main EPICS system. More specs, documentation, link to Andrea's talk (GSI, Dec 2009).

ALERT! The recommended LabVIEW version to use is 2009.

ALERT! Look into COSYLAB module for CompactRIO:
