CHIPS IAC Run 5-28-08

Delay from gun is about 400 ns gate width between 400 and 800 ns

Tune 4 MeV electrons into Experimental Cell

Optics elements 45Q2, Bend2, L90Q1m L90Q2 are after the tungsten converter.

Here is an image of the transmission. Channel-2 minus Channel-4 (FC - flange).

Zero Degree Port.

Beam spot as a function of grid voltage knob setting -- not calibrated to voltage but reproducible. (Settings: 0.1, 0.15, 0.18, 0.2)

The 0.15 grid setting is nice. It does not saturate. Here we take slices in x and y and then fit gaussians to the intensity curves. We observe that 35 mm is 244 pix.
