TOF Measurement
Measured near S2 just before the chicane (upstream) and gap between QM6 and BM3 (downstream). SAD file gives it as a measurement of 13.357m to be confirmed by a tape measure on Monday. Using a TOF measurement of 296ns, this estimates the energy as 10.8MeV for the nominal condition.
The relative phase between the two DTLs are given by -10V for -90 degrees, 0V for 0 degrees and +10V for +90 degrees.
Chopper Gate Width 400ns. Trigger delay 2.5698ms with respect to master Trigger.
Files 1 to 7 have a single channel, while all the rest have both channels, where CH2 refers to scintillator 1 (upstream) and CH3 refers to scintillator 2 (downstream). Measurements for upstream were made by inserting Scintillator 1 in to the beamline. Measurements for downstream were made by Scintillator 2 with Scintillator 1 removed from the beamline. This was repeated for several Voltage settings.
They all start with tek00 + the following endings:

Foil Mounting
For 3 sides: Surface tension still destroys foils as it is being extracted from water. A fraction of the foil remains, but not smooth.
For 4 sides: Not suitable for FFAG as need a free side for the beam to go on and off from. Suitable however for Craig's experiment. Successfully mounted 5.2ug/cm2 foil using the towel over the washing line technique for a total thickness of 10.4ug/cm2. The extra side below ensures it is strong enough to remain intact once the surface water is broken. Single side not successful yet/may not be possible as the foil is to weak to support itself without some adhesion, like to itself.
