The length stabilization technique is dependent on use of a frequency-stable master laser. Such a laser is not yet available, but the University of Electro Communications (UEC) in Japan has a laser with very good long term stability. Therefore the test instrument was brought to Japan and a series of measurements was made using the UEC laser with the goal of verifying the accuracy of the length stabilization technique. The tests allowed us to set an upper limit on the delay variation in the stabilized path of about 70 fsec over 1 hour. It is possible that the system meets the ALMA goal of about 6 fsec delay variation (1.26 ?m fiber length variation) over at least 100 sec, but establishing this was beyond the limits of these tests.

Please make note of the following meeting on your calendars. The JAO-IPT Meeting scheduled for Monday has been moved to the regular JAO Meeting on Thursday, 20th February. Please read Paul's note below carefully. The IPT meeting scheduled for next Monday, February 17, falls on an NRAO holiday. That meeting is re-scheduled for 15:30 UT on Thursday, February 20. We will have a joint JAO - IPT meeting at that time. I hope as many of the usual attendees at the Monday IPT meetings will be able to attend this joint meeting, the last chance we have to share news before the ALMA Board meets the following week.

Comparison data were also taken at Antofagasta, Santiago, Mitaka, and on board the aircrafts to/from the site. Significant enhancement of dose rates was found at the ALMA site: Measured gamma ray dose rate (including ~ 0.45 mSv yr-1contribution of terrestrial gamma ray) was 3.14 mSv yr-1at Pampa La Bola, and 1.70 mSv yr-1atSan Pedro de Atacama, respectively, whereas it was 0.99 mSv yr-1at Santiago. As for the neutron component, altitude dependence is severer: Measured neutron dose rates were 0.80 mSv yr-1at Pampa La Bola, and 0.25 mSv yr-1 at San Pedro de Atacama, respectively, whereas it was 0.01 mSv yr-1at Santiago. These values are even higher than world average dose rates at comparable altitudes, probably reflecting enhancement of incoming primary cosmic rays near the South Atlantic Anomaly. After correction for the effects of solar activity and indoor shielding, we estimate the occupational exposure of an 8?6 turno employee to be 2.0 mSv yr-1, which exceeds that of a typical worker engaged in nuclear fuel cycle.

This memo describes the architecture for the filterbanks that naturally lends itself to multi-resolution observing in multiple frequency bands. It is based on a cascade of polyphase filterbanks, this maximizes the signal to noise performance at the highest frequency resolution.
