Generated by ARS on 01/13/98 15:55:41 ACTION ITEMS LIST FOR SUPPORT TEAMS AND INFRASTRUCTURE Telescope : ESO NTT Create-date : 11/04/97 14:54:57 Problem Short Description : Water gets into the NTT building through the building seal when it rains or snows with strong wind. 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 : Responsible : Infrastructure Support Group Deadline : 01/10/98 09:00:00 Deadline Status : Closed on Time ________________________________________________________________________________ Telescope : ESO NTT Create-date : 11/04/97 14:59:20 Problem Short Description : Installation of HP-UX 10.20 on operational WSs and support of the installation of NOV97 release of VLTSW. Action : HP-UX 10.20 should be installed on wt5tcs, wa5tcs, wemmi, and wg5ops at the very beginningof the technical period of January 8-20, 1998. Support is requested (in particular from P. Glaves and R.Rojas) for the subsequent installation of the NOV97 release of the VLTSW. More details are to be found in the document "NTT Upgrade - Plan for technical activities during period 60" Action Log : Responsible : Software&Commun.Supp.T. Deadline : 01/10/98 09:00:00 Deadline Status : Closed on Time ________________________________________________________________________________ Telescope : ESO NTT Create-date : 11/11/97 17:36:24 Problem Short Description : Pointing model instability. Action : Optics and Mechanics Support Team should cooperate with the NTT Team in the investigation of this problem. Weekly reports are expected in the Action Log of this action. 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. 12/19/97 09:13:20 agilliot Dec 19, 97 a new short talk with Philippe has been done, a report with the first analysis results is to be expected during the coming days. The major pointing errors has been identified, it is related to the last strong earthquake. A residual error remains of about 6 arcsec and could be related to an active optic correction moving the main mirror (conditions of mirror total weight and force momentum not respected when correction is required at large zenithal distance). Once issued the report, most probably actions will be requested on The NTT team to take care of a proper log of the correction requirement, force distribution and pointing error ....) 01/06/98 17:50:58 gandreon Report has been issued by P Gitton.

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. Anyway, the deadline was not assigned because no member from Optics was present. 12/09/97 16:13:29 gandreon More troubles with the unit have been reported by the Telescope Team. It may become an urgent problem, therefore a proposal from Optics is expected. 12/15/97 19:01:26 agilliot Because no opticians will be present on the mountain on the coming idle time a solution is possible now: - exchange of the entrance slit unit by a old scanner intermediate slit. - calibration and alignment of the slit with the CES alignment laser. This will be a temporary solving until the April Overhaul. 12/16/97 18:28:54 gandreon Waiting decision from astronomer. 12/19/97 09:03:07 agilliot Decision from astronomer was against any change on the instrument during the run.
