Action : Seal to be modified. Since this requires the building to remain fixed for several days in a row, it can best be done simultaneously with another technical action during which building motion is suspended. Such a circumstance will occur from January 8 to January 10, 1998. A first part of the seal improvement work should take place then.

Action Log : 11/23/97 12:08:09 agilliot Nov 23, 1997 After preliminary discussions with NTT team members (Paul, Ricardo,...) , the NTT pointing instability has been investigated by Philippe since long time. WE first have to check with him what is the status of his study. Then we will inform him about the management decision of offering help from the opticians and mechanicians support teams. The OIC will support him at his request and eventually agreed on tests strategy to be applied. Alain 11/25/97 15:40:46 gandreon A sysmograph from Universita' de Chile has been installed and connected to the network for monitoring earthquakes. Philippe is still on leave. 12/01/97 18:14:02 agilliot Dec 1, 97 A first talk with Philippe has been done today, Philippe has done already several tests and results compilations showing few telescope features affecting the pointing. Further tests will be done during scheduled test time to confirm preliminary test results.

Deadline : 12/15/97 21:00:00 Deadline Status : Pending ________________________________________________________________________________ Telescope : ESO 360 Create-date : 09/28/97 15:59:12 Problem Short Description : The air-conditioning plant on 3.6m ground floor is the major source of CES vibrations Action : Make a study to identify all the functions performed by the air-conditioning plant on the 3.6m ground floor. Which functions are essential and which could be dismissed ? If only a few functions are essential, use of the huge and expensive plant could be superseded by installing small dediated units to condition the correspondiung rooms. Those could possibly be more cost-efficient and more easy to damp. Action Log : 10/14/97 10:38:28 gihle We are in the process to identify the main sources of the vibrations and we found that the fans are the main source. A first attempt changing the mounting absorvers was done by LWE and the results are positive. If it is proved , by RTH measurements, that there is an improvement, we are going to change all absorvers by new ones. 11/07/97 14:28:54 lgonzale test 11/07/97 22:59:03 lgonzale 4,5,6/11/97 L.Gonzalez / R.Tighe The functions performed by the air-conditioning plant have been identified and listed in order of importance: 1rst: Air-condition to a constant temperature, the CES coude room (critical). 2nd: Air-condition to a constant temperature the ADONIS Lab. coude room (not so critical). 3rd: Cool below critical temperature the CES computer room, and apparently also the 3.6m computer room (important). 4th: Cool the building (not critical in short term). 5th: Ventilate building, specially bathrooms and offices (not so critical in short term). ( The idea is to be able to at least turn off the plant, or parts of it, during observing time). The Coude Floor residual vibration frequencies,their normalized strengths, and their sources have been identified. Also the transmission (or gain) T from source-to-coude floor, has been measured. The following table summarizes the results: VIBRATION LINE(Hz) SOURCE NORM. STRENGTH GAIN T (in coude labs.) (of line in coude labs.) (T = line coude / line air-plant) -------------------------------------------------------------------------- --------- 6 - 8 Wind/Dome/Cage 0.05 sensitivity to source much decreased after pier clean 12-13 Activity in Coude/Cage 0.1 sensitivity to source increased after pier cleaning 20-22 C9 0.3 3 24 C3 1.0 1 30 C3 + C5VR 0.2 0.1 32.4 C7 + C8 0.5 2 43-49 C3 + C7 + C8 0.3 0.5 -------------------------------------------------------------------------- --------- (Note: C# corresponds to different units of the Air-Conditioning Plant identified as CUBICO#). 11/11/97 09:18:22 gihle A report was sent by LWE regarding the air conditioning system of the 3.6m. This report will be forwarded to M.Kürster for his knowledge.

Action : In January, we will test the New IR WFS (RASOAR) for the adaptive system ADONIS. A previous action point was to make a cover for the ADONIS bench. We don't think that something will be made for the M9-Camera place which is under the bench. But this will be very useful to test the WFS during the day and will protect the M9.

Action : They need an overhaul. It should be carried out during next idle time. Action Log : 12/01/97 18:24:39 agilliot The CES general Overhaul is already planified for next year before the installation of the very long camera. The dismounting of the entrance slit will require a complete re-calibration of the jaw position as well as a new golbal instrument-telescope alignment check. It is a time consuming operation not scheduled for us. No opticians will be present during the next idle time end of december. According last week status , the slit failures occured only on remote control mode ? Day time test on local mode didn't shown slit mis-positionning (a week ago) What is the last status ? (I should remember the procedure to open an action point, after agreement between the involved teams...) 12/02/97 15:47:26 gandreon Note from GAN: teams should care about attending the Tuesday meeting.
