Day 1. December 3, 2007.
Who: Pierre, +?
Glass Slides at 10 cm, 30 cm, and 50 cm.
Brett says the electron beam onto the window is 1 mm in diameter. After it passes throught the water-cooled exit window (Al 1mm - Water 1mm - Al 1mm), the beam swells to 0.6mm and at 30cm it the beam spot size is 2cm.
Beam spot size mapping in x and y with the Faraday Cup (FC) for z = 30cm from Window.
We will move the table in or out depending on whether the beam spot size is greater or smaller than 2.0 cm. Translator table will be positioned at right position in z.
Linearity tests of the pickup coil and FC. We will just change the width of the pulse 80 ns, 100 ns, 150 ns, 300 us. 500 ns, 750 ns, 1 us, and 2us.

5 hours of beamtime
o Irradiate broken PbF2 Crystal for 0.5 h and check how the temperature rise.
o Place Crystals 1, 2, 3, 4 on translator table.
* Crystal 1: 2 hours
* Crystal 2: 1 hours
* Crystal 3: 1 hour
* Crystal 4: 0.5 hours
o Transparency Test (~3 hours)
o Blue Light curing (24 hours)
