Massachusetts Institute of Technology, et. al; Application(s) for
Duty-Free Entry of Scientific Instruments
Pursuant to Section 6(c) of the Educational, Scientific and
Cultural Materials Importation Act of 1966 (Pub. L. 89-651, as amended
by Pub. L. 106-36; 80 Stat. 897; 15 CFR part 301), we invite comments
on the question of whether instruments of equivalent scientific value,
for the purposes for which the instruments shown below are intended to
be used, are being manufactured in the United States.
Comments must comply with 15 CFR 301.5(a)(3) and (4) of the
regulations and
[[Page 85943]]
be postmarked on or before November 18, 2024. Address written comments
to Statutory Import Programs Staff, Room 41006, U.S. Department of
Commerce, Washington, DC 20230. Please also email a copy of those
comments to [email protected].
Docket Number: 24-026. Applicant: Massachusetts Institute of
Technology, 77 Massachusetts Avenue, Cambridge, MA 02139. Instrument:
Narrow line width laser, FL-SF-1695-0.5.-CW. Manufacturer: Shanghai
Precilaser Technology, Co., Ltd., China. Intended Use: The instrument
is intended to be used as a single frequency laser system at 1695 nm
that will be used in quantum physics experiments at MIT for improved
optical atomic clocks and precision measurement using ytterbium
(\171\Yb). The 1695nm frequency is the Yb optical transition between
the ground state 4f\14\6s6p \3\P0 and the metastable state
4f\13\6s\2\5d(J = 2), where J represents the total angular momentum.
This transition allows the possibility of dual-mode optical lattice
clocks to further reduce the uncertainty from external level shifts, as
well as physics beyond the standard model (for example investigating a
potential mediating particle for forces between electron and neutron).
Justification for Duty-Free Entry: According to the applicant, there
are no instruments of the same general category manufactured in the
United States. Application accepted by Commissioner of Customs: August
8, 2024.
Docket Number: 24-027. Applicant: Massachusetts Institute of
Technology, 77 Massachusetts Avenue, Cambridge, MA 02114. Instrument:
Low noise laser system. Manufacturer: Shanghai Precilasers Technology
Co., Ltd., China. Intended Use: The instrument is intended to be used
for Sodium potassium molecules confined in optical dipole traps. Sodium
potassium molecules are fermionic molecules possessing large electric
dipole moment. Clouds of sodium-23 and potassium-40 atoms are first
laser-cooled into suitable ultracold temperatures and loaded into
optical dipole traps. A two-photon Raman process using the laser system
to be imported then binds pairs of sodium-23 and potassium-40 atoms
into deeply bound molecules in their absolute ground state. Direct
control of quantum states of molecules is difficult owing to the
structural complexity of molecules. Binding molecules from laser-cooled
and well-controlled atoms provides a more feasible alternative to
controlling and manipulating quantum states of molecules. Justification
for Duty-Free Entry: According to the applicant, there are no
instruments of the same general category manufactured in the United
States. Application accepted by Commissioner of Customs: August 27,
2024.
Docket Number: 24-029. Applicant: Harvard University, 1033
Massachusetts Avenue, Cambridge, MA 02138. Instrument: Narrow Line-
width laser. Manufacturer: Shanghai Precilasers Technology Co., Ltd.,
China. Intended Use: The narrow linewidth (<2kHz), ultralow noise
(intensity and phase), large tuning range (>1nm) seed laser at 1591 nm
will be used as a seed to be doubled down to 795 nm. The seed laser
will be used in a quantum physics experiment at Harvard for laser
cooling and trapping experiments for Rubidium atoms to explore quantum
physics research. The research work enabled by this system is part of
the training of graduate students, undergraduate students, and
postdoctoral research fellows. Justification for Duty-Free Entry:
According to the applicant, there are no instruments of the same
general category manufactured in the United States. Application
accepted by Commissioner of Customs: August 23, 2024.
Docket Number: 24-030. Applicant: University of Michigan, Naval
Architecture and Marine Engineering, West Hall RM 126, 1085 S
University Avenue, Ann Arbor, MI 48109. Instrument: Wave Generator
System. Manufacturer: Van Halteren Technologies Boxtel BV, Netherlands.
Intended Use: The instrument is intended to be used to study ship
motions in water waves. Ship models in fresh water are to be
investigated. The experiments to be conducted will involve the creation
of model scale ocean waves. The objective is an engineering
understanding of wave mechanics and the response of ship metrics.
Justification for Duty-Free Entry: According to the applicant, there
are no instruments of the same general category manufactured in the
United States. Application accepted by Commissioner of Customs: April
10, 2024.
Docket Number: 24-031. Applicant: University of Chicago, 929 E 57th
Street, GCIS ESB41, Chicago, IL 60637. Instrument: Fiber Laser.
Manufacturer: PreciLasers, China. Intended Use: The instrument is
intended to be used to study the Cold molecular Nuclear Time-Reversal
Experiment (CeNTREX), a collaborative physics experiment between
University of Massachusetts Amherst, Columbia University, Yale
University, University of Chicago, and Argonne National Laboratory. The
goal of the CeNTREX project is to shed light on the reasons for why
there is more matter than antimatter in the Universe through the
measurement of properties of the thallium-205 nucleus. Justification
for Duty-Free Entry: According to the applicant, there are no
instruments of the same general category manufactured in the United
States. Application accepted by Commissioner of Customs: August 27,
2024.
Docket Number: 24-032. Applicant: University of California, Santa
Barbara, 2509 Broida Hall, Santa Barbara, CA 93106-9530. Instrument:
Low Noise Laser Amplifier. Manufacturer: Shanghai Precilaser Technology
Co., Ltd., China. Intended Use: The instrument is intended to be used
in a cold atom experiment at the University of California, Santa
Barbara, for optical trapping and manipulation of cold lithium-7 atoms.
It will be seeded by 100 nW 1064 laser and will produce 100 W output
power. The low relative intensity noise (RIN) of this laser amplifier
is critical, because the intensity noise contributes a lot to the
stability of the optical traps, and the atom interferometry experiment
is very sensitive to the noise of the optical traps. Justification for
Duty-Free Entry: According to the applicant, there are no instruments
of the same general category manufactured in the United States.
Application accepted by Commissioner of Customs: September 17, 2024.
Docket Number: 24-033. Applicant: Harvard University, 17 Oxford
Street, Jefferson 158, Cambridge, MA 02138. Instrument: High Power
Single Frequency Fiber Amplifier. Manufacturer: Connet Laser Technology
Co., Ltd., China. Intended Use: The high power (30 W), single frequency
fiber amplifier system 1908 nm will be used in a quantum physics
experiment at Harvard for optical tweezer trapping of rubidium-87
atoms. The available laser power will allow many more of these atoms
(thousands) to be controlled than previously demonstrated (hundreds).
This platform will allow the study of larger quantum systems with
properties and fidelities far exceeding smaller systems. Justification
for Duty-Free Entry: According to the applicant, there are no
instruments of the same general category manufactured in the United
States. Application accepted by Commissioner of Customs: September 18,
2024.
