Goodman Startup/Shutdown Guide

Goodman High Throughput Spectrograph

Startup/Shutdown Guide

March 2010

Pre-Startup

The following steps may or may not be required, depending on the state of the system.

  • Make sure that all of the lens covers are off.
  • Make sure that the Goodman Camera Electronics are on. This can be checked from the ECS VNC Viewer and Remote Power sub-panel. If the camera electronics are not on, turn them on. If this is successful, you should hear three rapid beeps over the dome microphone  You should also see the Remote Power sub-panel indicator for the camera electronics switch from "off" to "on".
  • Make sure that the Goodman Motor Electronics are on. This can also be checked using the ECS VNC Viewer and Remote Power sub-panel. If the motor electronics are off, turn them on.  The Remote Power sub-panel indicator for the motor electronics should switch from "off" to "on".
  • Go to Rm 109 and log the balance pressure of the CryoTiger. It should be at about 190 psi if the cooling has been turned off. The balance pressure should be around 0 psi if the cooling is on. Log this number and the date on the sheet provided.
  • Power up soaric4 (139.229.15.134). If soaric4 has been shutdown, you will have to power cycle the ECS VNC Viewer Remote Power sub-panel for soaric4 twice, fairly quickly. A "ping" command should let you know when soaric4 is up and running. If this does not work, somebody will have to go to the dome and manually cycle the power on soaric4.  The Remote Power sub-panel for soaric4 should be "on".
  • Log on to soaric4 using the vncviewer from some other computer. The linux example is below:
    vncviewer 139.229.15.134 -Shared &
    Password: ********
    The password can be obtained from the TelOps staff (soaropsATctioDOTnoaoDOTedu) or the Instrument Scientist (spointsATctioDOTnoaoDOTedu).
  • If soaric4 has been re-booted, you will need to log on as "Observer". The password is the same as the observer account for OSIRIS. This password can be obtained from the TelOps staff (soaropsATctioDOTnoaoDOTedu)  or the Instrument Scientist (spointsATctioDOTnoaoDOTedu).
  • Log on to soaric7 using the vncviewer that is appropriate for your program. The linux example is below:
    vncviewer 139.229.15.137:<n> -Shared &
    Password: ********
    The display number <n> and password can be obtained from the TelOps staff (soaropsATctioDOTnoaoDOTedu) or the Instrument Scientist (spointsATctioDOTnoaoDOTedu).
  • Check the disk space on soaric4 by double-clicking on the "My Computer" icon. Highlight "Local Disk (C:)". Right-click and select "Properties". If the disk is almost full, please contact TelOps (soaropsATctioDOTnoaoDOTedu) or the Instrument Scientist (spointsATctio.DOTnoaoDOTedu) so they can delete older data.
  • Check the disk space on soaric7 by issuing the command "df -h" from a terminal prompt. If the /home3/observer disk is close to full, contact TelOps staff (soaropsATctioDOTnoaoDOTedu) or the Instrument Scientist spointsATctioDOTnoaoDOTedu.

Starting SI Image SGL D

  • Start SI Image SGLD from the Program Files Tab in the Start Menu.
  • Select "GOODMAN.SET" and click on "OK".
  • Initialize SI Image to bring up the CCD settings.
    • Check "Use Saved Configuration Parameters"
    • Open the settings file and select "GOODMAN.SET" (Sometimes the previous step does not work and Goodman needs to be re-initialized).
    • Make sure that the Cooling is turned on.
    • Open the CCD Camera Status window and make a note of the "CCD Chamber Pressure" (Use the same log sheet in which you logged the CryoTiger Balance Pressure). If the CCD Chamber Pressure is too high (> 0.1 Torr), you probably need to let the dewar completely warm, pump the dewar, and start cooling.
  • Pump the dewar if needed.
  • Repeat the above steps to turn on the cooling system.
  • In SI Image SGL D window, click on the Operate button/menu tab and click to start the TCP/IP server.
  • In the SI Image SGL D window, click on the View button/menu tab and turn off the "Auto Z Scale" feature.
  • In the upper right corner of the SGL D window, change the tab to the right of "Acquire Image 1" from "Light Exposure" to "Triggered Acq".

Starting the LabView Applications

  • Make sure that the transfer to soaric7 is working.
    Open the "My Computer" icon on the Desktop and see if "ic7home3" on "SOAR Data Samba Server" is present.
    If it is not open, click on the "My Network Places" icon on the Desktop and then click on the "ic7home3 on SOAR Data Samba Server" icon. The Instrument Scientist has the logon and password information.
  • Click the "Remote Transfer to soaric7" LabView shortcut on the Desktop and start the application by clicking on the white arrow.
  • Open the Goodman controls by clicking on the "GSP_Main" LabView shortcut on the Desktop and start the application by clicking on the white arrow.
  • Check the camera panel. If a green button is present for "Connection Open/Getting Data" in the upper left of the GUI, Goodman "sees" the SI Image camera control software and a TCP/IP connection is available to take data. You can confirm this by clicking on the "Obtain Camera Status" button. During a normal startup of the GSP Main GUI the Camera Temp will read "0". If the TCP/IP connection is operating, clicking on the "Obtain Camera Status" will show the latest temperature. If Goodman is cooled, the CCD Temp should be -106.5. If the CCD Temp does not update, you will need to check the SI Image SGL D window and make sure that a TCP/IP connection is open.
  • Click on Main tab and logon;
    Use the account appropriate for your observing program (i.e., BRAZIL, CHILE, MSU, NOAO, OTHER, or UNC) with the password provided by your institution.
  • Click the User tab and go to "Home Systems" Select Home all. You should see the dark green lights change to yellow on the control panel as systems are being homed. Upon a successful homing of the systems, all lights should be bright green.  If there are any red lights, you will need to log out of GSP Main and shutdown and cycle the power on the Goodman motor electronics.
  • After the camera is homed, start the flexure correction by clicking the flexure LED. It should change from dark green to bright green.
  • Change the readout from Port B to some other readout mode and then back to Port B readout, if possible. It is important that you do this before selecting an observing mode (i.e., Imaging 1x1, Spectroscopic 1x1, etc). Sometimes, Goodman will not readout properly unless this step is taken.
  • Select Gain and Readout Setting. These values are given in the table below. The default is 100kHz ATTN3, but as with the Port readout, it needs to be changed to another value before it is initialized correctly.
  • Select the imaging or spectroscopic mode in which you want to work.
  • Make sure that the "Save As" type is "I16 FITS".
  • Set up the grating and camera angles for your observations. The pre-defined modes are listed below.

Shutdown

At the end of the night, the observer and TelOps staff should do the following:

  • Observers:

    • Logout of the Goodman GUI. This is found under the Main tab.
    • Shutdown the instrument motors. This is also found under the Main tab and will store all of the mechanisms in their home position.
    • Create a directory on soaric4 (Goodman Data Acquisition computer) in C:\Data for the night of your observations (YYYY-MM-DD). Move all FITS files to this directory. Do not move the DO_NOT_DELETE_FROM_THIS_DIRECTORY file.
    • Create a directory on soaric7 (Goodman Data Anaylsis computer) in /home3/observer/GOODMAN_DATA/<PROGRAM> /YYYY-MM-DD, where <PROGRAM> is one of [BRAZIL, CHILE, MSU, NOAO, OTHER, or UNC].
    • Move the FITS files from /home3/observer/today to /home3/observer/GOODMAN_DATA/<PROGRAM> /YYYY-MM-DD.

  • TelOps:

    • After the logout and shutdown are done, the power to the Goodman Electronics box should be turned off on the remote power control panel.

  • IC7 Shutdown and/or Rebooted:

    • If soaric7 is rebooted or shutdown, the postproc (PPROC) process to move data to the NOAO Science Data Archive (SDA) needs to be restarted.
    • To restart PPROC, open a vncviewer to soaric7.ctio.noao.edu:8 (the VNC password is the same as for SOI).
    • Open a terminal window.
    • Execute the command
      ~/APPROOT/PPROC/exe/PPROC &
    • The PPROC command should now be restarted. One can take a test image and see if it appears in the list of "Last Processed Files".
