Diff for "BoloChkList"

This document describe the checks and test that must be done before and during the Bolometer pool, as well as the frequency needed for these tests.

The tests are divided into different groups, as they supposed to be carried by different groups of the IRAM staff (operators, AoDs, or Rxs)

OPERATOR CHECKLIST

• Bolometer temperature

AOD CHECKLIST

• Teach the observers on the general aspects of the observation even the expert MAMBO observers (weekly):

  • CookbookPako.

  • When to switch to heterodyne
  • What is a spiky scan
  • Not to open a second monitor at flexible@mrt-lx3:monitor/

• Do a backup of the DAFS (daily)

• Observations on absorber ((AbsorberObs, at least once per week!)

  • Do when the weather is too bad even for heterodyne observations.
  • Do if the scans are too spiky

RXs CHECKLIST

• Check the resistance
• Check battery voltage
• Check the Bias voltage

PROBLEMS AND SOLUTIONS

This is a quick guide through normal problems that appeared in the past and the possible reasons and solutions.

• PROBLEM	REASON	SOLUTION
  Bololog is not updated	goPool has not been sent	Ask the operator to do so
  Mopsic Monitor is not working	There is other monitor running and the DAFS files have been corrupted	Stop the second monitor and recreate the DAFS
  ABBA does not start getting data	Wobbler is not wobbling	Ask the operator
  ABBA does not start getting data	Wobbler works fine but the signal did not reach ABBA	Check the cable connections with ABBA
