You can find it off the Accelerator Main Menu (Monticello). Click on the second menu pop-up on the Data Acq line and you'll get a menu of Datacubes; select the 'Hall A 1C12 OTR Datacube'.
Note that the device isn't completely automated. The MCC operator must (among other things) insert appropriate attenuators to keep the camera from saturating. If the 'DataValid' field is a red 'No', then the data are useless.
(I see that the 'Current' field seems broken on this screen. Just
cosmetic, or is there a more up-to-date version of the GUI?)
