2000 NIST Time and Frequency Seminars

June 13 - 16, 2000

The Regal Harvest House Hotel
1345 28th St.
Boulder, CO 80302

A variety of modern electronic systems depend critically on precise timing or
an ultra-stable frequency reference.  The clocks and oscillators in such
systems must therefore be characterized carefully.  This seminar focuses on
common methods of measuring and interpreting oscillators and clock performance
and how these results affect overall system performance.

Participants will first learn the specialized measurement techniques for
quantifying frequency stability and spectral purity of an oscillator.  Second,
typical commercial oscillators and atomic frequency standards will be described
with explanations for their composite parts.  An overview of methods of
timekeeping and synchronization will follow, along with an introduction to
available time and frequency services.  Finally, present-day levels of
performance will be outlined along with prospects regarding the future.

Who Should Attend
This seminar is for beginning mathematicians, engineers, scientists, laboratory
technicians educators, managers and planners involved in the application and
use of high performance time and frequency systems.  It is particularly
appropriate for those who are or might be responsible for certification of
oscillator performance at levels where traceability to national standards is a
useful part of this certification.

Registration Information
The registration fee is $1200 for a combined seminar (In past years the seminar
was divided into Level I and  Level II seminars).

Fee includes lecture notes, continental breakfasts, three lunches,
refreshments, a reception and the latest version of STABLE for Windows
(software for frequency stability analysis).

Class size is limited.  Attendance will be on a first-come, first-served basis.

Deadline for registration and/or cancellation is May 30, 2000.

Boulder is located about 50 miles northwest of Denver International Airport
(DIA).  Transportation to and from Boulder is available by rental car,
limousine, or bus.  Most rental car companies have facilities at DIA.

The Super Shuttle Boulder, a limousine shuttle, leaves DIA every hour on the
hour arriving at Boulder hotels/motels in about 70 minutes.  The round trip
fare to hotels is $36.  Reservations are suggested.  The last shuttle leaves
DIA at 10:00 p.m.  Phone: (303) 444-0808.

A regional bus service, the RTD, provides transportation between DIA and
Boulder.  Buses leave every half-hour to an hour depending on the time of day. 
The buses run between 6:15 a.m. and 11:15 p.m.  Trip time is about 90 minutes,
with a final stop at the Boulder bus station.  The one-way fare is $8.

All hotels/motels are within walking distance of the National Institute of
Standards and Technology.

Local Boulder taxi service is also available.

Driving Directions
As you leave the airport, continue on Pena Blvd. to I-70.  Proceed west to a
sign for I-270 Cheyenne (next right).  Stay on I-270 until it merges with
I-76.  As you transition from I-270 to I-76, you need to be in the left hand
travel lane to merge onto US-36 West.  Once you are on US-36, it will be about
a 20-minute ride to Boulder and the Baseline Road exit. 

To locate NIST: Turn left at Baseline, proceed to the first traffic light (27th
Way) turn left, and proceed across Broadway into the Department of Commerce. 
The NIST visitor parking lot is located at the corner of Millikan Road and
Compton Road.
