After the mirror washing few weeks ago, suspicion is that water enter in the cells and dammage them ... at dismounting and a lubrification is needed Action Log : 10/26/00 2:33:23 PM gandreon Many more are still missing. Overhaul of a single actuator takes one day. 11/2/00 2:21:53 PM gandreon Deadline changed for remaining actuators (most urgent ones have been overhauled). 2/8/01 2:36:47 PM gandreon Some 10 actuators have been maintained. 3/30/01 11:00:11 AM gandreon New tool is being tuned. New deadline. 5/24/01 2:47:25 PM gandreon So far 36 have been maintained. 6/21/01 2:42:46 PM gihle There are 6 left to finish this work.

Action : we will need an "astro" account on wt5tcs, wa5tcs, wemmi, wsofi, wg5pl, wg5dhs (in addition to the already available astro@wg5off). This account should be in the vlt group and configured for using the VLT softw (i.e. envirnment set, etc). Except on wg5off, they will be used only through remsh commands sent via buttons, panels and menus, not through direct login. Action Log : Responsible : Software&Commun.Supp.T.

Then, SWC will check the system configurations, the routing, and perform any other test necessary to devise a solution. If the bottleneck will be located in the router to the backbone, a purchase of a different model will be considered (if justified). Responsible : Software&Commun.Supp.T. Status : New Deadline : Deadline Status : Not Assigned ________________________________________________________________________________ Telescope : ESO 360 Create-date : 12/30/99 1:14:33 PM Problem Short Description : Tube against parasitic light for CES Very Long Camera Action : A tube is required for the CES VLC to baffle straylight. As was present with the old Long Camera a tube is required that contains the camera mirror and extends beyond the folding mirror to baffle light. It needs to have a provision for easy access to the Hartmann mask such as a slidable door, or equivalent. Action Log : 1/13/00 2:26:57 PM gandreon More analisys is required. Tube may not be the best solution and it will be an heavy job. Currently the main source of parassitic light seems to have been cut (all LEDs off in Fiera). 2/3/00 4:43:18 PM gandreon Tests performed by R Tighe were satisfactory. To be confirmed by Martin. 2/10/00 5:22:45 PM gandreon A temporary solution has reduced parassitic light by a factor of 9. Therefore a permanent one should be devised. Deadline to be negotiated. 3/2/00 2:51:58 PM gandreon Proposal is for end of April. 3/9/00 4:26:07 PM gandreon Design ready. To be approved by Martin Kuster. 3/16/00 3:08:31 PM gandreon One source of light has been descovered and eliminated shoielding the fiber carrying data to/from Fiera. Action on hold unitl confirmed by Martin that now there is no more parassitic light. 4/6/00 3:29:52 PM gandreon Two protections have to be built, one for 45 degrees mirror and one for the grating. Deadline changed by the Director. 10/26/00 2:33:54 PM gandreon One ready. One nearly ready. 10/31/00 1:21:08 PM gihle Protection was installed. 11/16/00 2:17:15 PM gandreon It will be completed during next turno. 11/28/00 4:39:05 PM weckert Grating cover is mounted 1/4/01 2:14:18 PM gandreon Modification are needed. Back to assigned status. 1/11/01 1:43:01 PM gandreon Nearly ready... 2/1/01 1:58:37 PM gandreon To be finished next week. 2/8/01 2:39:04 PM gandreon To be finished by end of April. 5/3/01 2:38:19 PM gandreon To be completed next week. 5/10/01 3:03:59 PM gandreon The tube is installed. The grating protection still missing (low priority). 6/1/01 9:33:12 AM gandreon To be completed this week. 6/14/01 3:04:22 PM gihle To be accepted by the team and optician.

Action : Some sort of device to stop the water flux should be devised. Action Log : 5/3/01 2:40:02 PM gandreon Three special valves has been ordered. 6/1/01 9:40:18 AM gandreon Delivery is very late. GIH should check with C&P. 6/11/01 8:53:43 AM gihle The delivery has been confirmed by the 20th of June. However, the existing valve of a cooler that is not used was removed and installed in the 3.6m cooler. This together with a calibrated presostat that cut the system to prevent water flow were tested. The actual equipment will have the following characteristics : - In case that the circuit is obstructed, due to a non connected connector the valve will deviate the flow in bypass, preventing any possibility of a broken line or connection. - If a line is cut the presostat will cut the system. The maximum amount of water that can be spilled is 190cc - The equipment has to pumps that allows water flows of 0.5 lt/min to 3.3 lts/min and output pressures between 1.12 to 2.2 bar - The equipment for a proper functioning needs to be pressurized to 1 bar. 6/28/01 4:19:46 PM gandreon To be tested during next test time (8-12 July) Responsible : Mechanics Support Team Status : Completed Deadline : 7/11/01 11:00:00 PM Deadline Status : Pending ________________________________________________________________________________ Telescope : ESO 360 Create-date : 4/19/01 3:10:55 PM Problem Short Description : Cable holder beneath GP carriage does not move smoothly.

Action : Optical quality of all WFI filters should be measured. Action Log : 11/8/00 3:16:27 PM agilliot This action concerns two parts: - optical quality check of all WFI filter with point source focal reducer device to be implemented on the optics lab (a check of the tracking filter could be done) - improvement of all tracker filters by removing the spacer and installing a proper inclined shim to orientate better the filter with the out of axis beam. Time available to perform this time consuming operation could start in january Therefore the deadline must be around end of February at the earlest 11/9/00 2:25:06 PM gandreon First useful idle period is in January. A couple of periods required. 12/30/00 7:55:00 AM agilliot Optical bench to be prepared suring the second week of January 1/11/01 8:16:29 AM agilliot as scheduled the optical bench will be prepared during this turno 1/16/01 2:28:41 PM agilliot Optical bench ready . a first OIII filter was tested in parallel beam and found with large defoc !!!! more tests to be done next turnos ... pls 2p2team .... 4 filters will be done each days ..... starting next tuesday ... 1/25/01 9:16:09 AM agilliot as foreseen, three filters have been completed - IQ check (too are not good) - tracking filter improved (filter stack with high viscosity optical oil) the operation require almost the full day .... and the perspective of 4 filters per day seems ok .... 2/8/01 7:49:06 AM agilliot During this turno, 11 filters were characterized. It's at least represent a 1/3 of the available filters. Not only the ESO numbered filters are measured. On time for the end Of March 2/15/01 8:31:13 AM agilliot 12 new filters measured this short turno 2/28/01 8:22:16 PM agilliot New measure campgain on mid March 3/16/01 10:54:41 AM gihle 50% is done , however , so far 5 are not correct. This will be inmediately informed to the users. It was informed that also the guiding filters are improved. All this will come in a report 3/20/01 11:25:50 AM agilliot pre analysis of the images shown assymetry altready on the reference image . The bench setup had to be improved ............ using pinholes but then stray light level get too high .... and it is in phase to be improved by now no filter were measured ..... due to this point The deadline will have to be moved to finish the campaign in April during the down time .... with access to the allway use I filter 3/22/01 3:49:53 PM gandreon Urgent. Qualitative data already available to be transmitted to TT for immediate publication in the WEB. 4/19/01 3:00:23 PM gandreon Delivery may be delayed. 5/10/01 10:55:23 AM agilliot qualitative data delivered ..... requiring full moon period of WFI free of observer to complete action 5/10/01 3:06:18 PM gandreon New deadline set accordingly. 6/7/01 10:19:44 AM agilliot 13 filters measured ..... 4 are still scheduled for today to finish the verification. Several filters are bad and will be reported by email. The complete reduction of the data for a final report will require more time, after using IDL to be installed on line in the optical office 6/28/01 4:23:10 PM gandreon Dealine extended for the preparation of final report.

Action : As discussed in the last LSMM (29 June), we would like to know the resources and time-scales involved to install a simple (manual!) rotation of the Grism (0 degrees and 90 degrees) with WFI at the 2p2. This modification might also possibly involve ISG and the Electronic Teams. Action Log : 7/5/01 2:46:46 PM gandreon There are design considerations to be clarified before this point can be assigned. It seems that the grism cannot be rotated without loosing the guiding capability.
