I am working with Kirsten *Insert link* again today, and the lab we are doing is the speed of light. Today, we are going to get the experiment set up, and account for the "time walk" which can leave a systematic error in the experiment. Next week we'll be taking our final runs.


===Equipment===
* Tektronix TDS 1012 Oscilloscope
* Bertan Model 215 High voltage power supply
* Ortec TAC/SCA Module (Model 567)
* Harrison Laboratories Power Supply (Model 6207A, 160V, 0.2A)
* Canberra Delay Module (Model 2058)
===Set Up===
We followed along with Alexandra's notebook, here [[http://openwetware.org/wiki/User:Alexandra_S._Andrego/Notebook/Physics_307L/2009/10/12]] to connect the cables, following her procedure we:
* The "A" connection of the photomultiplier tube (PMT) to the top input of the delay module.
* The output of the delay module to a BNC T-splitter
    * One side connected to the channel 1 input on the oscilloscope
    * The other to the "Stop" input of the Time-Amplitude Converter (TAC).
* The output of the TAC to the channel 2 input of the oscilloscope.
* The "-HV" connection of the photomultiplier tube (PMT) to the "-HQ" connection of the Bertan Power Supply (PSU).
* The "Start" input of the TAC to the cable attached to the LED.

Speed of Light Lab, Day 1

I am working with Kirsten *Insert link* again today, and the lab we are doing is the speed of light. Today, we are going to get the experiment set up, and account for the "time walk" which can leave a systematic error in the experiment. Next week we'll be taking our final runs.

Equipment

  • Tektronix TDS 1012 Oscilloscope
  • Bertan Model 215 High voltage power supply
  • Ortec TAC/SCA Module (Model 567)
  • Harrison Laboratories Power Supply (Model 6207A, 160V, 0.2A)
  • Canberra Delay Module (Model 2058)

Set Up

We followed along with Alexandra's notebook, here [[1]] to connect the cables, following her procedure we:

  • The "A" connection of the photomultiplier tube (PMT) to the top input of the delay module.
  • The output of the delay module to a BNC T-splitter
   * One side connected to the channel 1 input on the oscilloscope
   * The other to the "Stop" input of the Time-Amplitude Converter (TAC).
  • The output of the TAC to the channel 2 input of the oscilloscope.
  • The "-HV" connection of the photomultiplier tube (PMT) to the "-HQ" connection of the Bertan Power Supply (PSU).
  • The "Start" input of the TAC to the cable attached to the LED.
