Tests performed during the heavy maintenance (2007.06.20)

TableOfContents

Goals

Identify the origin(s) of the "acceleration" problem in MAMBO2

People

Pico Veleta: DJ, SL, SN, JP

Methods

Inclinometer installed on the Mambo2 platform

Results

  • Inclinometer measurements for two on-off measurements with the Cascade and the Basic controller.

  • On-off measurements with the offsets in elevation: 360" (scan 47, Cascade) and 440" (scan 50, Basic)

  • An extra weight was put on the bolometer platform (scan 51)

  • Measurements of electrical peak with the oscilloscope during an on-off measurements with the offsets in elevation (scan 53).

No correlation was found between the beginning of the scans where the extra noise peaks appeared and the electric activity. A peak frequency of 5 sec was observed but which may be related to the air conditioned system.
