Following a routine review of the study by an independent data monitoring committee DMC , Novocure was informed that the pre-specified interim analysis for the LUNAR trial would be accelerated given the length of accrual and the number of events observed, to date. The DMC also stated that it is likely unnecessary and possibly unethical for patients randomized to the control arm to continue accrual to patients with 18 months follow-up. The DMC recommended a reduced sample size of approximately patients with 12 months follow-up which it believes will provide sufficient overall power for both primary and secondary endpoints. The DMC recommended no other changes to the design of the trial. Novocure remains blinded to all data.Due to the standard behavior of these atoms, this independent RF measurement method provides direct traceability to SI-defined constants.
Description The first fiber-coupled vapor cell for E-field measurements using Rydberg atoms. Credit: NIST Calibrated radio frequency RF electric field probes and antennas are currently limited by a complex, indirect traceability path and require a complex calibration — which presents a chicken-and-egg dilemma. Probes must be calibrated by placing them in a known electric field, while a precisely known electric field is only realized using calibrated probes. Borrowing a technique from atomic spectroscopy, electromagnetically-induced transparency EITwe can Electric Field Lab atoms as a noninvasive field probe for directly SI-traceable, self-calibrated RF electric field measurements over a huge range frequency.

Article source Project Goals The Rydberg atom-based sensing technique has shown promise for many applications beyond RF field probe calibrations. We are currently exploring: Fundamental RF Field Metrology — Atom-based microwave field measurements are independent of the Electrc calibration method. We are exploring the extent to which Rydberg atom-based field probes can improve field probe calibrations and push the limits of RF field metrology. RF Camera — Formed from an array of Rydberg sensors, the RF camera will be able to measure the magnitude and phase of an RF Electric Field Lab at multiple points in a low-invasive package that reduces distortion of the field.
Communications Reception — the Rydberg atoms can act as electrically small antennas and detect the modulation of a carrier wave. They can detect and demodulate AM, FM, and phase modulation over a broad range of carrier frequencies — making them a promising platform for advanced communication receivers.
Blackbody Radiation Characterization — Electric Field Lab excited Rydberg atoms are very sensitive to external fields and can sense changes in thermal radiation. We have a project to explore the limit of using Rydberg spectroscopy to measure and calibrate blackbody radiation. RF Power Metrology — We have two Fieeld for advanced RF power metrology, using both Rydberg atom measurements as well as photon pressure. These two methods can span a much larger dynamic range of traceable power measurements, from nW — kW, than traditional calorimeter-based measurements.]
