3.0 Instrument Status and Science Support

 

 

3.1 Flight Events and HETG Instrument Status

 

            The HETG continues to function with no outstanding issues.

 

There were 9 targets observed in 11 observation intervals by the HETG in April 2002. One target, Capella, is an HETG Calibration observation and will be analyzed when data are available (early May.) Two of the targets are in the HETG GTO program and will be examined in detail by the HETG group.

 

The HRMA PSF, which is crucial to the HETG’s high resolution, continues to be stable based on occasional analyses of the width of the ACIS frame-transfer streak in bright point-source HETG observations. Observations of PKS 2155-204 and Cygnus X-1 were recently analyzed and added to the FWHM plot, shown on next page.

 

3.2 Science Support to CXC, SWG, etc.

 

            E0102 images were provided to Project Science / Weisskopf for use in Structure and Evolution of Universe talk.

 

         Participated in Chandra Quarterly review at OCC, Cambridge MA.        


 

The HRMA PSF core width is monitored by measuring the FWHM of the ACIS

frame-transfer streak. Over two years of data show a very stable FWHM.

4.0 GTO Science Program

 

4.1 Observations and Data status

 

Progress in the GTO program observations and data analyses are noted in the Table of Appendix A.

 

4.2 Science theme progress

 

The HETG GTO science efforts span a range of “science themes” given in the list below. In each month’s report progress and plans in one of these themes will be highlighted, in addition to the terse incremental progress notes given in the Table of Appendix A. For each listed theme the date of its last progress reporting is also given for reference.

4.3 HETG-related Software: Development, Evaluation, and Support

 

In the process of carrying out the HETG GTO science program, the HETG scientist make use of existing analysis and modeling software and are engaged in helping to modify current and design future software. Notable efforts in this direction will be described here in future report issues.

5.0 Systems and Engineering Support

 

5.1 Documentation and “Knowledge Capture”

 

Attended Dan Shropshire’s demo of Chandra “document” database during the Chandra Quarterly review.

 

5.2 Spares Retest and Test Instrumentation

 

1. Vacuum Storage Gratings are due for re-test. The test is delayed because of failure of the Vacuum Gauge Controller. The controller was returned to the manufacturer for repair. The manufacturer has not yet given an estimate of the repair schedule, but the MIT estimate is two weeks or less.

 

2. The four computers which are part of the X-GEF and LR test instruments will no longer be supported long before the end of the planned Chandra mission. We have begun a low level effort to identify spares as other computers in CSR are replaced with more powerful versions. We anticipate minimal hardware costs.

 

3. The primary archival machine, named "caliber", operates on the Sun OS4 operating system, which is no longer supported. We are still operating on Sun OS4 because the software is configuration controlled. We have to perform additional manual steps to manage data storage because the volume of data accumulated is a challenge for OS4. We anticipate operating another computer on Solaris in parallel, so that when "caliber" fails, we will have confidence in the replacement hardware and software.

 

4. The Labview software for the MAC's was written by a now defunct outside vendor. We are working on upgrading the documentation.

           

5.3 Anomalies, Insert/retract, etc. Support

 

No actions this month.

 

 

6.0 Management

6.1 Program Office & NASA Support

 

            Supported monthly Chandra telecon and 9th Chandra Quarterly Review at OCC, Cambridge.

 

Responded to question about GFE equipment list, contract attachment D – will finalize modifications to

Attachment D soon.

 

6.2 MIT-internal management activities

 

Just the usual.

 

7.0 Open Issues, Problems, etc.

 

 

There are no known critical open issues or problems regarding the HETG.

There are no outstanding requests for travel or equipment.

 

Thanks to MSFC for timely approval of the recent request for Dr.Lee’s foreign travel.
