In order to operate the CCD, it needs to be cooled down first.
(images of startup screen, where to find cryotel and archon screens, highlight parameters to change)
We apply constant cooling to the detector using the CryoTel and PID-regulated heating with the Archon to get the detector to -100C.
Bring up the CryoTel and Archon screens under the qRIXS tab in the RIX home screen.
CryoTel:
Hit the "Power" button to start cooling the detector down. The minimum output power allowed by this device is 60W, and that alone will bring the camera down to colder temperatures than we want. So do NOT increase power. And DO NOT press "ON" or the CryoTel will try to get to the target temperature using its PID.
Archon
Archon controls are on 2 screens currently. The "parent" screen (left) is accessed through the home screen (labeled "CCD"), and the "child" screen (right) is accessed by pressing "STA5200". Power, bias voltage, and heater controls are on the child screen. Under "Power", turn power and bias voltage on. Under "Heater", set the target temperature to -100C and turn the heater on. Here are the other heater settings, these should not be changed.
The detector takes ~1hr to cool down completely.Note that everything here is "expert mode", users (and POCs for the most part) should not need to access all of this information. Controls group is working IOCs with interlocks to simplify CCD operation.
Running camera in DAQ
Note: make sure to "Stop" acquisition when changing settings, and "Start" after to apply changes. (image highlighting Acquire button)
| Settings to change | 1d | 2d |
|---|---|---|
| Readout Mode | FVB | Image |
| Bins | 1, 1 | 1, 1 |
| Image Size | 4800, 1 | 4800, 1200 |
| Fixed Rate | 100Hz | 1Hz |

DAQ/AMI:
NOTE: everything in the above screens is "expert mode". Users (and POCs for the most part) should not need to access all of this information. Controls group is working IOCs with interlocks to simplify CCD operation.
