# Physics307L F07:People/Gleicher/e diffraction

__DH 2__The first day of the experiment the equipment was not operating according to the lab manual, and therefore we spent the day troubleshooting the CRT and voltage supplies.

Here is a link to a diagram of the CRT

A write-up of the initial troubleshooting methodology: Physics307L F07:People/Gleicher/Notebook/070910

After Bill Miller discovered that an extra voltage was required on the CRT (5-12 Volts in parallel with heater voltage), we proceeded to take data Physics307L F07:People/Gleicher/Notebook/070917.
