Project: BELLE 
Subject: APVDAQ + telescope 40 MHz transparent mode (cooling?) 
Run Number: run013

Belle DUT, tranparent mode
HV=80V, 40 MHz, beam on, 120 GeV
6 samples
chiller set to 13 deg.

beam position:  p-side: APV2 of Origami, n-side: between APV1 and 2 of Origami (center of sensors), beam spot: 9x9 mm
JP-module is hit at APV3, module seems to be on a higher position than in past beam test (eventuelly flipped)

APVDAQ and telescope runs are not synchronized

trigger rate: about 300 - 500 ev / spill

there was probably no water flow throught the pipe of the origami module during this run --> must be repeated
