Running unpolarised hydrogen.

V14 was closed sometime during the initial setup of the unpolarised system. Ernie noticed this and the holding field was ramped down and V14 opened.

Genya deteremined this happened around 18:00 Tuesday so runs 8362-8369 have V14 closed. Runs 8370-8389 have V14 open.

Otherwise smooth data taking. Injecting at 130 mA dumping at 80 mA. Typical lifetime 25 minutes.

All runs crunched or crunching. 250 K event run takes about ~1/2 hour to collect data and ~8 hours to crunch which means the 16 processors of the spuds can just keep up.

Genya is now setting up ABS for polarised D.
