Next Meeting:

     Thursday, 9 May 2002, 7:30 P.M. (Refreshments and Social at
     7:00 P.M.) at the new MITRE2 Building in McLean, Virginia.
     DC SIGAda and Baltimore SIGAda will feature the following
     presentation:

Title:

     Ada in Nuclear Fusion Research at the National Ignition Facility
     or
     How Does a Really Big Laser Hit a Very Small Target?

Abstract:

     The National Ignition Facility (NIF) at LLNL will fire 192 laser
     beams at a tiny fuel capsule,compressing it to a small fraction
     of its original size and heating a portion of it to 100,000,000
     degrees. Under these conditions, the fusion reaction will ignite
     and more energy will be produced than was delivered in the
     laser beams. NIF experiments will produce conditions of high
     energy and density similar to those found at the center of the
     Sun (and other stars).

     These lasers are controlled by software written in Ada that uses
     CORBA for communication and coordination. This presentation
     will describe the software architectures and technologies used
     to control a system of over 60,000 discrete parts. But mainly, it
     is an opportunity to show slides from a consulting trip to the
     facility under construction.

Presenter:

     Interface Systems, Inc. in Reston, Virginia. After joining
     Objective Interface in 1994, he has been responsible for
     architecting, designing, and implementing the products in the
     ORBexpress line of high-performance, real-time CORBA
     Object Request Brokers.

     Victor received a Master of Science in Numerical Science from
     Johns Hopkins University and an A.B. in Physics and
     Mathematics from Cornell University. He is a member of the
     ACM and the IEEE Computer Society.

Venue/Directions

     MITRE2
     Room 1N100 A/B
     The MITRE Corporation
     7515 Colshire Drive
     McLean, Virginia 22102-7508


Directions:

     MITRE2 is on Colshire Drive just inside the beltway south of
     Route 123.

     Several people could not find Colshire Drive for the March
     Meeting. There was construction on Route 123 and the street
     sign for Colshire Road had been removed. As the street on the
     North side of Route 123 is called "Scotts Xing", it was not
     apparent where Colshire Road was located.

     The elusive Colshire Road: Colshire Road is located on
     Route 123, East of I-495 and West of the Dulles Access
     Highway. Going Northbound on 123 from I-495, Colshire Road
     is located 2 stoplights on the right. Going Southbound on 123
     from the Dulles Access Highway, Colshire Road is located at
     the first stoplight on the left. Once on Colshire Road, MITRE2
     is the building immediately in front of you. A tiny traffic circle
     is designed to take you to the front of MITRE2 and to MITRE1
     (the Hayes Building). The directions below route you to the
     parking garage behind the MITRE2 Building. This is a logical
     left-hand turn at the traffic circle. After the turn, MITRE2 will
     be on your right.

     From I-495 south of Route 123 (Dolley Madison Boulevard):
          1. Take Exit 46B (McLean, Route 123);
          2. Go North onto Route 123;
          3. Turn right onto Colshire Drive (at second light);
          4. Take third right off of the small traffic circle;
             (a logical left hand turn);
          5. Proceed ~ 50 meters; Turn right into parking garage.
          6. Visitor Parking is located on Levels 2 and 3
             (the walkway to the lobby is on Parking Level 2)
          7. If door is locked, contact Security using phone by door
             (at entrance to MITRE2 from the Parking Garage)
          8. Check in with Security at Security desk in lobby
             (You will need a photo ID)

     From Dulles Access Toll Road or I-495 north of the Dulles
     Access Toll Road:
          1. Take the Dulles Airport Access and Toll Road to Exit 19;
             (From I-495, this is labeled "To East I-66");
          2. Take Exit 19A;
             (following signs to Route 123 South, Tysons Corner);
          3. Bear right onto Route 123 (towards Tysons Corner)
          4. Turn left onto Colshire Drive (at first light);
          5. Take third right off of the small traffic circle;
             (a logical left hand turn);
          6. Proceed ~ 50 meters; Turn right into parking garage.
          7. Visitor Parking is located on Levels 2 and 3
             (the walkway to the lobby is on Parking Level 2)
          8. If door is locked, contact Security using phone by door
