Minutes Feburary 14th:
- Grigory presented his studies on the laser beam-line in the building. The main conclusion is that the laser must come on the same plane as the electron beam line if one want to use a coupled mirror mount for the transport.
- He also explored alternative location (eg in the surface building on the first floor). However, the transport to such a location would be very complicated:
- Either need to go through the crane shaft.
- Or need to drill the radiation shiedling (2m thick with 45 degrees angle).
- disfavoured.
- Maik presented the curves of the temperature and humidity readins since 2012.
- The system in Jena was able to operate with a temperature stabilisation of about 22+-1 degrees.
- The dispertion of the humidity is much larger but they were using some settings for summer and winter.
- Cover dust, and AC should be stabilized aorund the laser area (specs in the twiki).
- Conclusion that such a system could be done in HERA West for approx 50k.
- Crane can lift up 1 ton.
- No restriction to come from the top.
- Alex and Falk will come in Hamburg on March 3rd evening and on the 4th, they will live at 16h00 that day.
- Need to converge on a new timeslot for the meeting, mornings dont work very well for Karsten.
