PIMP

Documents

Documents available in the NIKA2 private wiki documentation page (https://wiki.iram.fr/wiki/nika2/index.php?title=NIKA2Documentation):

• Cahier des charges contains some drawing giving an idea on how the frame is mounted on the HWP pedestal.
• PIMP control computer documentation is the document written by Aurélien explaining how to start and control the PIMP. It is already printed at the telescope, on the NIKA2 table in control room, and in the PIMP box. You can skipp the first part on the Raspberry and start ready from User Manual on p5.
• PIMP purpose and optics simulations is a presentations I had prepared almost 6 years ago but never showed, because I wanted to combine its presentation with presentation of the results from Juan... It explains very quickly the purpose of the PIMP in the main lines, and based on Zemax simulations explains the purpose of the convergent lens and the divergent lens you will find in the PIMP box.
• Finally the Video and photos show the start of a PIMP scan and pictures with different orientation of the PIMP (once the PIMP is installed, use the crank handle on the side opposite to the cryostat to rotate it, and the pin break to maintain id at a given orientation)

How to setup the PIMP with the acquisition

when the pimp is plugged on the NIKA2 network, it sends various kind of data to the network (scan start and stop, the speed, frequency and so on). These data can be read by the NIKA2 acquisition, providing that there's the correct variable declarations in the ini file. The Pimp is treated by the acquisition like an "instrument", exactly like each Nikel board is treated. If you look in the folder where the ini file are you will find 3 ini files that contain PIMP specific variable declarations. You will have to use them. I'm sorry, I have to leave now. If you are not so sure about these ini file you can have help from Juan, Martino, and Alessandro. You can also experiment them, to try figuring out by yourself how it works, no harm can't be done (I think ;-)). We can also exchange more tomorrow.
