title: The importance of anomalous ion effects in pole erosion simulations of a magnetically shielded hall thruster

description: Magnetic shielding in Hall thrusters has been shown to protect the discharge channel walls from ion sputtering thereby eliminating this process as a failure mode. Some low yet measurable erosion has been observed however on surfaces along the side of such thrusters facing the near-plume plasma. With measured rates below 100 μm/kh, NASA’s Hall Effect Rocket with Magnetic Shielding (HERMeS) has featured a low sputtering yield cover of a few millimeters in thickness to protect the front magnetic poles from erosion. In recent work, we argued that anomalous ion heating due to lower hybrid instabilities can play a major role in the erosion of these surfaces. Here we show that such heating indeed contributes to the erosion both directly and indirectly, through various processes in the plume region, and present models that capture them. Comparisons between numerical simulations and wear tests performed at NASA on a Technology Demonstration Unit (TDU) of HERMeS show very good agreement when all these processes are accounted for. We also provide pole erosion predictions for a Qualification Model of the thruster currently under development by NASA’s industry partner Aerojet-Rocketdyne which, from the perspective of front pole wear, is nearly identical to HERMeS. The predictions are made at discharge voltage and power of 600 V and 9-12 kW, respectively and include the recession of the front pole covers as a function of time. We find that the adopted design will protect the front magnetic pole for more than 35,000 hours, which is current throughput requirement for this thruster with 50 % margin.

title: Flattening laser frequency comb spectra with a1 high dynamic range, broadband spectral shaper2 on-a-chip

description: Spectral shaping is critical to many fields of science. In astronomy for example, the detection of exoplanets via the Doppler effect hinges on the ability to calibrate a high resolution spectrograph. Laser frequency combs can be used for this, but the wildly varying intensity across the spectrum can make it impossible to optimally utilize the entire comb, leading to a reduced overall precision of calibration. To circumvent this, astronomical applications of laser frequency combs rely on a bulk optic setup which can flatten the output spectrum before sending it to the spectrograph. Such flatteners require complex and expensive optical elements like spatial light modulators and have non-negligible bench top footprints. Here we present an alternative in the form of an all-photonic spectral shaper that can be used to flatten the spectrum of a laser frequency comb. The device consists of a circuit etched into a silicon nitride wafer that supports an arrayed-waveguide grating to disperse the light over hundreds of nanometers in wavelength, followed by Mach-Zehnder interferometers to control the amplitude of each channel, thermo-optic phase modulators to phase the channels and a second arrayed-waveguide grating to recombine the spectrum. The demonstrator device operates from 1400-1800 nm (covering the astronomical H band), with twenty 20 nm wide channels. The device allows for nearly 40 dBs of dynamic modulation of the spectrum via the Mach-Zehnders , which is greater than that offered by most spatial light modulators. With a smooth spectrum light source (superluminescent light source), we reduced the static spectral variation to ∼3 dB, limited by the properties of the components used in the circuit. On a laser frequency comb which had strong spectral modulations, and some at high spatial frequencies, we nevertheless managed to reduce the modulation to ∼5 dBs, sufficient for astronomical applications. The size of the device is of the order of a US quarter, significantly cheaper than their bulk optic counter parts and will be beneficial to any area of science that requires spectral shaping over a broad range, with high dynamic range, including exoplanet detection.

title: DPCA-based Doppler radar measurements from space: Effect of system errors on velocity estimation performance

description: The Displaced Phased Center Antenna (DPCA) method of clutter cancellation for ground moving target detection from airborne platforms has been in use for a number of decades. Application of the DPCA method for spaceborne Doppler weather radar velocity estimation was suggested in 2007. The initial description and analysis of the technique was followed several years ago by demonstration using a multi-antenna airborne radar. Recent reviews of methods and technology for spaceborne cloud and precipitation radar have also mentioned possible use of DPCA. However, to date, analyses of the application of DPCA to spaceborne Doppler weather radar have assumed that the two antennas are identical, including perfect alignment, and that the DPCA condition is well-satisfied. This study uses simulation to examine the effects of relaxing these assumptions. The simulation method and its validation are discussed, with companion analytical calculations in the Appendix. Next, simulations are used to show the effects on the Doppler estimates from errors in pointing and positioning relative to the ideal DPCA conditions using idealized scenes. The DPCA technique is relatively robust to possible errors, indicating that a practical DPCA radar system can provide precise Doppler measurements from space.
