Procedure

On Thursday June 8th, Nitrogen was added to the TPC, such that the total mixture contained 20 ppm. This was completed around 16:00 and run 42322 began. Then around 19:30 a sample was taken and the TPC fields were set to 5.45 kV and 29.45 kV. Nitrogen production then commences with run 42343

For completeness, I present the slow control parameters for the nitrogen fill. Obviously the humidity sensor doesn't show anything substantial, but the temperature and flow curves contain useful information.

Data Set <-- -->	Start Run	End Run	Polarity	Start Date	Start Time	FADC	Condition	Quality	Comment
10	42343	42530	mu-	6/8/2006	19:46:18	HS	N2 doped	G
9	42322	42342	mu-	6/8/2006	16:10:20	HS	N2 doped, but TPC p=10.25	G

Line: 36 to 37

2	42342	42343				HS	GC: (24+-1) ppm, O2 < 1ppm, Filling: (21 +- 1) ppm	G
3	42570	42571				HS	GC: perfect agreement with previous measurement	G	at end of the nitrogen measurement
