University of Colorado Boulder, et al.; Notice of Consolidated
Decision on Applications for Duty-Free Entry of Scientific Instruments
This is a decision 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).
Related records can be viewed between 8:30 a.m. and 5:00 p.m. in Room
3720, U.S. Department of Commerce, 14th and Constitution Ave. NW.,
Washington, DC.
Comments: None received. Decision: Approved. We know of no
instruments of equivalent scientific value to the foreign instruments
described below, for such purposes as each is intended to be used, that
was being manufactured in the United States at the time of its order.
Docket Number: 12-053. Applicant: University of Colorado Boulder,
Denver, CO 80203. Instrument: HF2LI Lock-In System. Manufacturer:
Zurich Instruments AG, Switzerland. Intended Use: See notice at 77 FR
74647, December 17, 2012. Comments: None received. Decision: Approved.
We know of no instruments of equivalent scientific value to the foreign
instruments described below, for such purposes as this is intended to
be used, that was being manufactured in the United States at the time
of order. Reasons: The instrument will be used to measure detected
near-field signals scattered off an Atomic Force Microscope (AFM) tip
in a scattering-Scanning Near-field Optical Microscope (s-SNOM). The
instrument will detect the magnitude and phase of the light scattered
by an AFM tip to measure the electromagnetic near-field of optical
antennas, plasmonics in metals and semiconductors (including graphene),
photonic crystals, and other nanoscale spectroscopy applications. The
instrument has the ability to fully digitize the measured signal and
analyze it at 50 MHz, as well as the ability to demodulate many
frequencies at once, which is essential to the measurement technique.
Demodulation at 50 MHz is necessary because the AFM tip oscillates at
350-300 kHz, and higher harmonics (5th or 6th) of this oscillation must
be measured to isolate the near-field signal.
Docket Number: 12-054. Applicant: Purdue University, West
Lafayette, IN 47909-2036. Instrument: DD Neutron Generator.
Manufacturer: NSD Fusion, Germany. Intended Use: See notice at 77

FR 74647, December 17, 2012. Comments: None received. Decision:
Approved. We know of no instruments of equivalent scientific value to
the foreign instruments described below, for such purposes as this is
intended to be used, that was being manufactured in the United States
at the time of order. Reasons: The instrument will be used to determine
the behavior of produced scintillation light and ionization electrons
of low energy nuclear recoils of Xenon, as well as to compare the
combination of energy released in these two channels to energy released
in electronic recoils of the same energy. The scintillation and
ionization signals are studied in a detector vessel that lies
underneath 5 meters of water, thus the instrument needs to be water
tight. To study the scintillation light and ionization behavior of
liquid xenon to neutrons from a mono-energetic neutron source with
energies close to 2.5 MeV, each neutron interaction must be resolved
separately, and thus arrive at most once every millisecond. The
instrument has been proven to show less than a few hundred counts per
second when operated at low voltage, and thus meets this requirement.
Docket Number: 12-057. Applicant: Massachusetts Institute of
Technology, Cambridge, MA 02139. Instrument: Fast Ferrite Tuner.
Manufacturer: AFT Microwave GmbH, Germany. Intended Use: See notice at
77 FR 74647, December 17, 2012. Comments: None received. Decision:
Approved. We know of no instruments of equivalent scientific value to
the foreign instruments described below, for such purposes as this is
intended to be used, that was being manufactured in the United States
at the time of order. Reasons: The instrument is part of a magnetic
field-aligned Ion Cyclotron RF antenna, which is used to automatically
follow the load variation in real time and make the antenna system load
tolerant. The instrument's unique specifications are its frequency
range of 50-80 MHz and 5 MW circulating power.
Docket Number: 12-058. Applicant: Regents of the University of
California, Lawrence Berkeley National Laboratory, Berkeley, CA 94720.
Instrument: Neodymium Iron Boron (NdFeB) Magnetic Block-HXU Model
(Vacodym 776). Manufacturer: Vacuumschemelze GmbH & Co., KG, Germany.
Intended Use: See notice at 77 FR 76456, December 28, 2012. Comments:
None received. Decision: Approved. We know of no instruments of
equivalent scientific value to the foreign instruments described below,
for such purposes as this is intended to be used, that was being
manufactured in the United States at the time of order. Reasons: The
instrument will be used to study matter on the fundamental atomic
length scale and the associated ultrafast time scales of atomic motion
and electronic transformation. The NdFeB magnet blocks must be of high
magnetic field density to achieve the base spectral range. They must
also be of high uniformity in order to achieve Free-Electron Laser
(FEL) saturation. In addition to meeting these requirements, the unique
capabilities of this instrument are expanded spectral reach, x-ray
beams with controllable polarization, and ``pump'' pulses over a vastly
extended range of photon energies to a sample, which are synchronized
to the Linac Coherent Light Source II project's ray probe pulses with
controllable inter-pulse time delay.
Docket Number: 12-063. Applicant: University of Pittsburgh,
Pittsburgh, PA 15260. Instrument: Dilution Refrigerator with 9/2/2T
Vector Superconducting Magnet. Manufacturer: Leiden Cryogenics, the
Netherlands. Intended Use: See notice at 77 FR 76456-57, December 28,
2012. Comments: None received. Decision: Approved. We know of no
instruments of equivalent scientific value to the foreign instruments
described below, for such purposes as this is intended to be used, that
was being manufactured in the United States at the time of order.
Reasons: The instrument will be used, in conjunction with the
instrument imported under docket 12-065, to develop ways for preserving
quantum information in a way that is immune to a wide variety of
decoherence mechanisms, to program fundamental couplings at near-atomic
scales, for the quantum simulation of ``metasuperconductors,'' and to
develop new mechanisms for the transfer of quantum information between
long-lived localized states and delocalized states. The samples to be
studied are a thin layer of LaAIO3 (LAO), grown on
SrTiO3, which undergoes a metal to insulator transition when
the LAO thickness is greater than 3 unit cells. The unique features of
this instrument are the ability to cool samples to T<50 mK using
cryogen-free cooling where possible, an integral cryogen-free 3 axis
vector magnet (>5/1/1 T), an integral large field magnet (>18T), the
ability to rotate the orientation in a large field, and scanning probe
microscopy capability at base temperature (T<50mK). These features
enable the sample to be cooled below the superconducting transition
temperature (Tc~200mK), to be rotated in any orientation relative to
the magnetic fields, allow the investigation of the large spin-orbit
field present in the samples (Bso~15T), and on nanometer size scales
gate, modify and probe nanowire devices and quantum dot arrays.
Docket Number: 12-065. Applicant: University of Pittsburgh,
Pittsburgh, PA 15260. Instrument: Motorized Two Axis Sample Rotator for
Dilution Refrigerator. Manufacturer: Attocube Systems, Germany.
Intended Use: See notice at 77 FR 76456-57, December 28, 2012.
Comments: None received. Decision: Approved. We know of no instruments
