 3  This repository is a final attempt of giving a final shape to a crappy code I am using to run a miniature dilution refrigerator.
 4  At the moment (beginning of June, 2025), the code is very specific, everything is hardcoded and I am the only person that knows how it work.

 6  Here a little description of my setup (is it even useful?):
 7  
 8  **Description of the readout electronics:**
 9  
10      - 2 CTC1000 (A and B), responsible for the management and readout of one 7He system each. 
11        The channels for both are:
12          In1 = 4He switch thermometer
13          In2 = 3He switch thermometer
14          In3 = 4He pump thermometer
15          In4 = 3He pump thermometer
16          Out1 = 4He pump heater
17          Out2 = 3He pump heater
18          AIO1 = 4He switch heater
19          AIO2 = 3He switch heater
20      
21      - 1 Lakeshore 224, responsible for the readout of 3 thermometers:
22          D2 = 40K plate
23          D3 = 4K plate (2 wires) --> should be on the mainplate
24          D4 = 4K plate (4 wires) --> should be on the fridge plate
25          
26      - 1 Lakeshore 372, responsible for the readout of 8 thermometers and the still heater:
27          1 = 3He head  (bottom connector)
28          2 = 4He head  (bottom connector) 
29          3 = 3He head  (top connector)
30          4 = 4He head  (top connector)
31          5 = Still
32          6 = Mixing Chamber
33          7 = Condenser 
34          9 = Mixing Chamber (added)
35
