New Items, Suggestions and Ideas with possible relevance to MDTs
1. A new Wire Tension Meter , proposed by Alexandr Volkov,
JINR Dubna
Here is some information about it (wtm1.txt,
wtm1.eps,
wtm2.txt).
For more detailed
information, please send email to: Alexandr Volkov
2. MDT "Negative High Voltage Treatment (NHVT)"
Shows promising results as a 'cure' against dark currents in ATLAS MDTs and
noise reduction in TDC spectra during data taking with the BOS98 MPI prototype
chamber at the CERN H8 testbeam;
U. Bratzler, H. Dietl, Jun-Sep 1999 (ATLAS Note in preparation.)
For more information, see these documents ( Test Facilities Meeting, 13 Sep.1999) or send email to Uwe Bratzler.
