CHIPIR

This page collects information that will be useful for the implementation of the new control system on CHIPR.

Background & Timeline

CHIPIR is a neutron instrument dedicated to the irradiation of microelectronics with atmospheric-like neutrons, on TS2. The CHIPIR web page describes the background to the instrument.

It was originally intended that IBEX should be piloted on CHIPIR, but commissioning of the instrument has taken longer than expected and, therefore, this idea has been shelved. Nevertheless, there is no reason why IBEX cannot be installed on CHIPIR at some future date.

CHIPIR Equipment

Note: Galil

Model: DMC2280

Other than the collimator, the only other quirk to CHIPIR’s galil 02 is that the jaws in/out axis uses a non-standard homing routine - galil_Home_JogForwLimit.dmc

Note: Filter Set

Driven by Beckhoff controlled motor.
See see Galil note

These are driven through TC using some variables for in/out readback and control. There is also some web HMI screen which IDD motion wrote which may now be defunct now that IBEX works with the filter set.

Note: Collimator

Driven by Galil controlled motor.

This runs some custom galil code but essentially does not accept moves like a normal motor. it has an encoder as an auxiliary feedback only ie. to see if it’s moving, but uses physical switches fed into the Galil’s digital ins for positioning. It uses a “read” thread that runs on thread 7 to monitor these during a move.
