It should be put into operations and proper behavious (pressures) should be checked. Action Log : 11/11/97 09:10:44 gihle Luis Weendegass made the check of the cooling system at the SOFI side in the NTT.The results are: 1) Cold water line pump in Service Room : Inlet pressure 1.5 bar; outlet pressure 4.6 bar. 2) In SOFI room : Inlet pressure in manifold 3.55 bar; outlet pressure in manifold 2 bar. In order to simulate an equipment and its lost of pressure, it was prepared a system with 4 connectors with a diameter of 4mm and 6 mts hose of 6mm diameter. The flow obtained in these conditions were of 7 lts/min. Water temperature can be considered between 0 and 5 degrees.

Action : Seal to be modified. Since this requires the building to remain fixed for several days in a row, it can best be done simulatneously 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 : A support and a tool are needed. Action Log : 09/30/97 16:30:11 rtighe R.Tighe & J.Roucher First; an easy portable target will be manufactured by Mech. support team, next turno (2nd week of Oct.). The purpose of this target is just in case an alignment check should be done on ADONIS and not have to dismount SHARP-COMIC. Second; ADONIS, SHARP and FP calibration unit are all installed and aligned in the lab. with all images and pupils conjugated. The 2500 resolution FP has also been installed to test alignment procedures (autocollimation) and calibration. We've discovered that FP calibration problems reported (too low light signal) were due to misalignment (wrong installation), and the autocollimation error (which led to move M9 last run) is of the order of 10Arcsec when FP properly installed. We are testing correction alternatives if this misalignment "must" be corrected. Finally, no matter what prefocal optics is installed on ADONIS-SHARP/Comic, NO OPTICAL COMPO- NENT (including the camera) NEEDS TO BE TOUCHED. By design, all components that have some degree of freedom to be moved, are to be controlled by the operator from the CONTROL ROOM. EVEN the FP autocollimation can be done moving the ON_OFF mirror, in this way not changing the the instrument alignment. SHARP/Comic alignment should only be done ONCE during installation no more. 10/28/97 15:54:49 gandreon To be checked by TT. 11/04/97 14:53:42 gandreon The tool is not ready.

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.

Because it is easier to check if a cable is good or not with an other good one. Therefore, if the cable is defectuous (as it append 3 times this week) it can be immediately changed, and we don't have to wait until it has to be repaired. Action Log : 10/07/97 18:03:15 gandreon Telescope team's electronics will check out which cables do not have spare (considering also EFOSC II).

Action : When the sky baffle is opened, the baffle does not always stay in its locked position. An inspection was made by mechanics several months ago, and they then stated that the axle needed replacement. The action required is to replace the axle, and ensure that the sky baffle locks solidly into the open position. Note: This point arose during the time in which no requests could be made to mechanics. Action Log : 10/02/97 09:16:32 gihle The main problem of the sky baffle cover is the impossibility to keep it safe in its open position. We suggest to place a magnet in order to once the cover opens, it will be kept in that position with this electro magnet. Once is necessary to close, the limit switch will activate the electro magnet in order to release it. The magnet will be installed by us, but the electric connections will need to be done by the Telescope Team. 10/07/97 17:37:34 gandreon Solution will be checked with MET electronics engineers before setting a new deadline (magnet has to be ordered). 10/14/97 10:40:45 gihle Parts required for the installation of the magnet are ready, we need the electronics collaboration. 10/21/97 16:09:56 gandreon Installation can proceed.
