        WORKSHOP on HIGH THROUGHPUT X-RAY SPECTROSCOPY 
                 September 30 - October 1 1996
                       FINAL ANNOUNCEMENT
    ------------------------------------------------------------------

The   Scientific   Working Group   for    the  High  Throughput  X-ray
Spectroscopy Mission concept  study   (co-chaired by Nick  White   and
Harvey Tananbaum) is organizing a two-day Workshop on  High Throughput
X-ray Spectroscopy to  be held  in Boston/Cambridge, Massachusetts, on
September 30 and October 1, 1996.

The Workshop will emphasize  invited talks on the important scientific
questions to  be addressed by High  Throughput  X-ray Spectroscopy.  A
list of  preliminary titles and confirmed  speakers appears below.  In
addition, there will be poster/display sessions for contributed papers
on related science and instrumentation topics; a subset  of the poster
papers   will   be  selected   for   contributed   oral presentations.
Proceedings of the Workshop will be widely  disseminated following the
meeting.  There  will be no registration fee.   Since the mailing list
we are  using is no doubt incomplete,  please feel  free to share this
announcement with potentially interested colleagues.

The baseline High Throughput X-ray Spectroscopy (HTXS) mission concept
provides ~15,000 cm^2 effective area at 1 keV, 6,000  cm^2 at 6.4 keV,
and 1500 cm^2 at 40 keV.  A resolving power (E/DE)  of at least 300 is
maintained across the 0.25-10 keV band, with a targetted resolution of
3000  at 6.4 keV.  The angular  resolution baseline is 15-30" (HPD) up
to 10 keV and 1-2' from 10  - 40 keV.  For  current information on the
HTXS mission concept study, please access our web page at:


http://htxs.gsfc.nasa.gov/

The  Workshop will   be  held  at  the  DoubleTree  Guest Suites Hotel
overlooking the Charles River (on the Boston side) about one mile from
Harvard Square.  We have reserved a block of rooms for  up to 3 nights
(from Sunday, September  29   through Tuesday, October 1)   for  those
needing accommodations for the meeting.  A special, reduced group rate
of $149.00 per night for a single, and $159.00  per night for a double
has been arranged with the DoubleTree Hotel.  Rates are subject to the
current 5.0% state tax plus 4.7% city tax.

We plan to hold a reception (hors d'oeuvres provided plus cash bar) at
the  DoubleTree   on Sunday  evening  from 6-9  PM.  We   will provide
coffee/juice/pastry  in  the mornings,   and beverage/cookies  in  the
afternoon (at no cost to participants).  Lunch  will be available each
day at the meeting site for a cost of ~$8.50.

PARTICIPANTS SHOULD  MAKE THEIR  OWN RESERVATIONS DIRECTLY    WITH THE
HOTEL.  THE REDUCED  RATE CAN  ONLY  BE GUARANTEED  AVAILABLE  THROUGH
SEPTEMBER 3 (although a limited number of rooms may still be available
at this rate through September 9).  To obtain the special meeting rate
mention  that  you   are  attending the Workshop    organized  by  the
Smithsonian.

The DoubleTree Guest  Suites hotel,  is located  at 400 Soldiers Field
Road,  Boston, Massachusetts  02134.   Phone (617) 783-0090, Fax (617)
783-0189. The hotel is 5 miles from Logan International Airport.  Just
off the  Massachusetts Turnpike, the  DoubleTree is  close to Boston's
museums,  historical sites, and universities.   Some special points of
interest located nearby  are: Harvard  Square, House of  Blues, J.F.K.
Library, Legal  Seafood, Museum of Fine  Arts,  Museum of Science, New
England Aquarium, and Quincy Market/Faneuil Hall.

Among many  fine   features,  each guest suite  includes:  livingroom,
bedroom and bath; refrigerator; complimentary  use of health club  and
indoor pool facilities; and courtesy hotel van to locations throughout
Cambridge and Downtown Boston.

Parking  is available at the hotel  parking garage, although a  car is
really  unnecessary  for   participants   staying at  the  Doubletree.
Meeting participants will be charged a  special, reduced $5.00 parking
fee for the day, or each time the garage is entered.
