Flasher Board Current Pulse 01/14/04

(Xu Zhai and Mark Krasberg)


Using Thorsten's code, we used the flasher board trigger for the first time. The start of the ATWD window can be adjusted in 25ns increments with Thorsten's code. DAC 0 was set to its maximum (4095) to blow up the window as much as possible. The ATWD position was adjusted so the current pulse was was roughly centered within it.

100 triggers were taken - the 100 histograms are overlaid onto one graph (hence the thick lines...).



The 40 MHz squre wave at the muxer is shown here:
The picture above is therefore something like 1.2 ns per bin
