Small Steps

Today I added a tap point for analog reading from the ion gauge. Pins 3 and 7 according to the manual.




Eventually I’d like to use the digital interface, but for now this gets the job done.

Next I added a proper connector to the bench-top power supply (pulled from an old PC):


This works a lot better than the wire jumper which kept falling out.

We received and tested the 100A/100mV ammeter shunt resister:

IMG_4085We will use this shunt to take current reading going into the superconducting magnet.

Next up we tested out the IGBT:


Using this schematic:


It successfully switched 10 mA. Next to try it with more amps.
