Action : Mechanical modification to the cover in front of the window may solve the problem. The problem is urgent since this is the period of the year that is most affected by condensation. We need a solution as soon as possible. Please move back the deadline! Action Log : 30 de December de 1998 12:43:50 PM gandreon Problem became urgent due to atmosferic conditions during summer. A prompt delivery is required by the TT. 7 de January de 1999 12:59:16 PM gandreon It only affect SOFI because SUSI has its own system (N2). 15 de April de 1999 5:51:49 PM weckert All parts are manufactured. During next turno the unit will be anodized and assembled and can be mounted in front of the SOFI window. 13 de May de 1999 4:29:51 PM gandreon To be installed on May 18-23. 20 de May de 1999 3:03:11 PM gandreon To be completed by June 30. 17 de June de 1999 2:47:16 PM gandreon Parts are ready for mounting. 28 de June de 1999 1:51:27 PM gihle The unit has been installed and it is working.

We were told that - workshop was too workloaded - the kind of boxes we always used until now at NTT are unnecessarily expensive and that it should be possible to buy some from a catalog . We therfore got a catalog from W. Eckert and after agreeing with Alain Giliotte we ordered 20 units of the model which better looked to fit our needs FOR TEST. It appears CLEARLY that these boxes are very cumbersome and even dangerous to contain filters, specially DM 8000 ones. So we still do not have a safe filter storing solution at NTT. Our ideal solution is to get maufactured manufactured anywhere 15 susi2 filter boxes ( 9 filters to arrive this year ) 5 emmi filte boxes ( spares ) 10 transparent lids ( to replace opaque emmi lids) The models we have in use now are satisfacory except opaque emmi and a little shape detail on susi2 lids. Action Log : 3 de February de 1999 2:09:13 PM gihle The time required to manufacture these boxes is : - To make the filter boxes, SUSI2 or EMMI : 3.5 hours each box plus cover. Total: 70 hours. - To make the transparent covers : 2 hours each. Total : 20 hours All material must be ordered under NTT budget. 11 de February de 1999 12:57:29 PM gandreon It will be carried out as background job. Few boxes are supposed to be delivered fairly soon. 7 de April de 1999 5:36:22 PM gihle Material for the fabrication has been ordered. We have not received it yet. 15 de April de 1999 5:53:33 PM weckert The material did not yet arrive in Chile 22 de April de 1999 3:32:03 PM weckert Material has arrived. Fabrication will start as soon as possible. 29 de April de 1999 4:21:08 PM gandreon The prototype is ready. 20 de May de 1999 3:05:01 PM gandreon Twenty boxes are ready. 8 de June de 1999 8:25:06 AM gandreon 15 boxes still missing. 8 de July de 1999 2:58:55 PM gandreon 10 boxes ready to be picked up.

Action : For the Calibration Plan of ADONIS, we need to measure the optical transmission of the bench, in the visible and in the infrared. We want to do it first in the lab., then to develop an easy procedure to be able to do it directly in the Cassegrain cage of the telescope, when Adonis is mounted. We need, among other things, a blackbody, an IR optical fiber. Related with the calibration plan, some characterization of the turbulence generator has to be done. [O. Marco for T360 Team].

Action : The support for the magnet that locks the skybaffle in the open position should be redesigned such that it is flush with the serruriers. This will allow the safety wire to stop the telescope before the support hits the floor (this happens at dec~-6 and when the telescope is in the extreme east).

Pizzella can provide further details). Action Log : 21 de June de 1999 10:50:47 AM rtighe Tests done with A.Pizzella clearly show that a simple adjustment of the HeAr lamp illumination lens is not the solution. The FEROS+B&C's cal. lamps illumination unit was designed to produce a ~15mm spot at the entrance of the B&C calibration optics. This was clearly too small so A.Kaufel increased the spot size by defocusing a bit some lenses. The lamps housing has an exit beam aperture of ~20mm. and it is now limiting the spot size. To increase the aperture diameter isn't so easy because the unit needs to be disassembled ( a day would be needed). It's a matter that needs to be studied with mechanics (W.Eckert). A modification of the HeAr illumination optics may be required as well. And the 2p2Team should schedule the work for some maintenance period. 24 de June de 1999 3:19:29 PM gandreon A new deadline has to be agreed after analysis from mechanics.
