Action : Replace one of the unused lamp with a new HgCdZnAr lamp. Action Log : 4/5/2006 7:29:57 PM ebarrios EFOSC2 IOT REQUEST: On behalf of IVO here with the reason why the HgCdZnAr lamp has to be added to the current set.. "---------------------------------------------------------------------- ----------------------------------------- Dear all, here's some output of our tests with the "new" EFOSC2 lamp. The 1st attachment shows a comparison of an arc taken with grism 7 and slit 1" and the usual HeAr lamp (blue line) and an arc taken with the new lamp (black line). The obvious difference is that there are two lines at ca. 3600 AA in the new lamp arc, which allow to better constrain the wavelength calibration in the bluest part of the spectrum. The 2nd attachment shows the arc of the new lamp with the Hg and Cd lines identified. The arc has been calibrated in wavelength using the solution provided by the old, HeAr, lamp. Using these lines, the 3rd attachment shows the difference between observed and true wavelength of the Cd and Hg lines. Obviously below 4000 AA the solution is bad at the level of 1.5 AA, i.e. more than 100 km/sec at these wavelengths. In conclusion, I would recommend to use this lamp for observations at the bluest spectral range ----------------------------------------------------------------------- ------------------------------------" Currently we are using four lamps, i.e. Quarz, He, Ne, Ar. The action request is to replace one of the other 3 lamps, then opto-mechanic mounting and PWR supply replacement and socket connections have to be done. Software and all the control hardware is there and working, but may be a re-wiring be needed. 4/25/2006 3:19:57 PM gandreon To be ready for next run of Efosc. 5/23/2006 12:23:41 PM amacchin Working on it Responsible : Engineering (Electronics) Status : Assigned Deadline : 7/20/2006 12:00:00 AM Deadline Status : Pending ________________________________________________________________________________ Telescope : ESO 360 Create-date : 5/9/2006 3:55:46 PM Problem Short Description : Lights in the dome may be turned on during calibration Action : Provide a remote interlock in the Ritz, as it was available in the old control room.

Action : We need to mount a 3DEX neutral density filter instead of the green filter in the carriage in front of the IMG guide camera to allow guding on very bright objects (i.e. Alpha Cen.) with an exposure time large enough to integrate over the speckles and to avoid saturation. The driver of this request is the improvement of the asteroseismology performances of HARPS. Action Log : Responsible : Engineering (Instrum.)

Consumption should not affect the main mirror support system that also makes use of this compressed air. 1/10/2006 3:19:19 PM gandreon Material is being prepared 1/20/2006 12:48:21 PM fselman A question to those involved: what mechanism will be used by the new system to filter out dust which we should not have on the dewar window? (just for completeness... this refer to the WFI CCDs...it is not mentioned anywhere in this ticket) 2/28/2006 2:52:36 PM gandreon Please answer the question in the previous comment. 3/5/2006 8:33:39 AM gihle The actual pressurized air is the one used in the supporting system of the main mirror. This air is dried and filtered at the service building. Once in the telescope basement there is a second water vapor trap and in the telescope a sub micron filter before entering the air supporting mechanism. The plan is to take air after this last filter or to install another filter before the last one in an independent hose obtaining the air from a T connection. 3/7/2006 4:18:06 PM gandreon Part ordered, in quantity sufficient for two installation. 3/28/2006 4:40:25 PM gandreon Material is arriving.

Action : To make this system independent from the telescope cooling by connecting it to an independent chiller Action Log : 12/6/2005 4:40:39 PM gandreon Since more cooling is required for GROND the use of a larger chiller is under consideration. 12/13/2005 2:44:34 PM gandreon Large chiller will be instatlled.

When inspecting the corrections sent by the TCS to the telescope we see that in RA most of the corrections have the largest acceptable value (0.5). This is because to accomplish a given offset on the sky the telescope has to rotate by a large angle when pointing to the south. Paradoxically, the closer to the south galactic pole we point the less critical the guiding becomes. This action point is to request that Software Engineering group implements the integration-loop-correction time concept used in other autoguiders to improve the guiding at these important positions (LMC, SMC). Action Log : 5/30/2006 12:01:31 PM jreveco Implementation of loop time and exposure time ready.
