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 they are expert MAMBO observers:
- When to switch to heterodyne
- What is a spiky scan
- Not to open a second monitor at flexible@mrt-lx3:monitor/
Do absorber observations (AbsorberObs) when the weather is too bad even for heterodyne observations.
Do absorber observations (AbsorberObs) if the scans are too spiky
RXs CHECKLIST
- Resistance
- Check battery 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
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
