This is a how-to for a single sensor. Ultimately, there will be two of these sensors at qRIXS. 

Devices involved:

  • Archon controller
  • CryoTel controller
  • Water chiller (small)
  • Sensor with cryotel coldhead
  • Laptop (PCxxxxx)

8 cable connections:

  • Water lines to from chiller x2
  • Glenair signal cable from flange to archon 
  • 1-to-3 breakout controls cable between CryoTel coldhead/flange and cryotel controller 
    • On the controller, one connection. 
    • On the coldhead/flange side, three connections: Two black connectors which go to coldhead, and one db9 connector that goes to the flange. 
  • Cable that goes from CryoTel controller to coldhead 
  • Cat5 from Archon controller to laptop
  • RS232 to USB cable from cryotel controller (RS232) to laptop (USB) 
  • Trigger cable to bottom BNC port on Archon


Navigating ArchonGUI:

  1. Run "./archongui -small" (the -small option allows for a re-sizeable window)
  2. File → Open → *whatever_name_of_config_file*.acf 
  3. Hit "Connect", "Auto Fetch", "Apply all"
  4. Turn "Power On" on lower right, this is bias voltage 
  5. In "Slot 3: HeaterX"
    1. Sensor C should be RTD1000
    2. Heater A parameters:
      1. Target: -100C
      2. Sensor: Sensor C
      3. Force: unchecked
      4. Limit(V): 25.0
      5. P: 50
      6. I: 1
      7. D: 10
      8. IL: 20
      9. Ramp enable: checked
      10. Ramp rate: 20mK/tick
    3. Hit "Apply" (*note: hitting "Apply" will reset any values the PID had accumulated up to that point, like a refresh)

Cooldown takes ~2hrs.


CryoTel Software:

*note: The cryotel has a PID, but we don't use it.  We use the other PID (via the Archon) that regulates the heater near/on the sensor.  Keeping pwout to a minimum (i.e 60) keeps vibrations to a minimum.

  1. Open new terminal: sudo putty /dev/ttyUSB0 -serial -sercfg 9600,8,n,1,N
  2. Commands
    1. View status: "status"
    2. Check cooler power: "pwout" (this should be 60. If not, set with "pwout=60") 
    3. Turn cryotel on: "cooler=power"
    4. Turn cryotel off: "cooler=OFF" (might need to enter this command more than once to actually turn power off)


--------Only applicable for bench testing-------------

Parameters on waveform generator:

  • Waveform: Pulsed mode
  • Frequency: 200Hz (or anything under 250Hz)
  • Pulse Height: 3.3V
  • Pulse Offset: 1.65V
  • Pulse Width: 1us 
  • Burst Mode: ON (lately it seems you must have it on to see anything on detector)
