Noise Performance Evaluation of the Candidate Digitizers for the MAJORANA DEMONSTRATOR (open access)

Noise Performance Evaluation of the Candidate Digitizers for the MAJORANA DEMONSTRATOR

The noise performance evaluation of the two digitizer cards being considered for the MAJORANA DEMONSTRATOR (MJD) is presented in this document. The procurement of the data acquisition electronics for the MJD is scheduled to happen this year. At the time of writing this document, there are two candidate digitizer electronic boards. One aspect that is being considered by the collaboration is the feasibility of using the MJD for dark matter searches. The feasibility of using the MJD for this application is going to be dictated by the ability of the demonstrator to reach sub-keV energy resolution. One of the potential sources of noise in the MJD is the data acquisition system. This document will is concluded with a recommendation for the final digitizer board by comparing the noise performance of the two electronics systems. Noise parameters such as the effective number of bits, input range linearity and signal to noise ratio are experimentally determined. The two digitizer cards feature different on-board digital signal processing and these features are compared. The experimental set-up was also used to identify sources of noise. This paper describes these sources of noise in the data acquisition system, along with mitigation strategies. Issues such as grounding …

Oral History Interview with Roger G. Anderson, March 16, 2012 transcript

Oral History Interview with Roger G. Anderson, March 16, 2012

The National Museum of the Pacific War presents an oral interview with Roger G. Anderson. When Anderson finished high school in 1943, he entered the Army Air Forces and trained initially at Miami Beach, Florida, then at Laredo, Texas, for gunnery school. Anderson describes the training involved at gunnery school and shares a few anecdotes. In July, 1944, Anderson and crew headed overseas. they were assigned to the 19th Bomb Squadron, 22nd Bomb Group, 5th Air Force. His squadron was nicknamed the Silver Fleet. To begin with, he was stationed in New Guinea and flew aome missions there. Eventually, his unit was assigned to Tacloban, bu teh area was too muddy for an airbase, so his unt was statioend at Angaur. From there, his unit evenually moved up to Clark Field on Luzon. In August, 1945, Anderson went home on leave after completing 48 missions. He anticipated being trained in B-29s, but the war ended while he was home on furlough and he got discharged in October, 1945. He used the G.I. Bill to go to college and eventually had a career as a teacher in Illinois.

Measurement/Evaluation Techniques and Nuclear Data Associated with Fission of 239Pu by Fission Spectrum Neutrons (open access)

Measurement/Evaluation Techniques and Nuclear Data Associated with Fission of 239Pu by Fission Spectrum Neutrons

This Panel was chartered to review and assess new evaluations of work on fission product data, as well as the evaluation process used by the two U.S. nuclear weapons physics laboratories. The work focuses on fission product yields resulting from fission spectrum neutrons incident on plutonium, and includes data from measurements that had not been previously published as well as new or revised fission product cumulative yield data, and related quantities such as Q values and R values. This report documents the Panel's assessment of the work presented by Los Alamos National Laboratory (LANL) and Lawrence Livermore National Laboratory (LLNL). Based on the work presented we have seven key observations: (1) Experiments conducted in the 1970s at LANL, some of which were performed in association with a larger, NIST-led, program, have recently been documented. A preliminary assessment of this work, which will be referred to in this document as ILRR-LANL, shows it to be technically sound. (2) LLNL has done a thorough, unbiased review and evaluation of the available literature and is in the process of incorporating the previously unavailable LANL data into its evaluation of key fission product yields. The results of the LLNL effort, which includes a preliminary …

Band Collapse and the Quantum Hall Effect in Graphene (open access)

Band Collapse and the Quantum Hall Effect in Graphene

The recent Quantum Hall experiments in graphene have confirmed the theoretically well-understood picture of the quantum Hall (QH) conductance in fermion systems with continuum Dirac spectrum. In this paper we take into account the lattice, and perform an exact diagonalization of the Landau problem on the hexagonal lattice. At very large magnetic fields the Dirac argument fails completely and the Hall conductance, given by the number of edge states present in the gaps of the spectrum, is dominated by lattice effects. As the field is lowered, the experimentally observed situation is recovered through a phenomenon which we call band collapse. As a corollary, for low magnetic field, graphene will exhibit two qualitatively different QHE's: at low filling, the QHE will be dominated by the 'relativistic' Dirac spectrum and the Hall conductance will be odd-integer; above a certain filling, the QHE will be dominated by a non-relativistic spectrum, and the Hall conductance will span all integers, even and odd.

Oral History Interview with Merton Bobo, March 16, 2010

The National Museum of the Pacific War presents an oral interview with Merton Bobo. Bobo was born in Greenfield, Maine 10 February 1926. Graduating from high school in 1943 he enlisted in the Navy. Following a six week boot camp in Sampson, New York he was sent to Jacksonville, Florida to attend radio school. Once he graduated, he was sent to Yellow Water, Florida for gunnery training. Upon completing the gunnery training, he went to Fort Lauderdale, where he began operational training in a TBM with a pilot and gunner. The crew stayed together during their combat tour. Upon completion of the advanced training the crew went to San Diego where they joined VC-90. Going to Hawaii, they were trained in the use of rockets and torpedoes. The crew was assigned to the USS Steamer Bay (CVE-87) and began making patrols and practice landings. They joined a task unit and sailed to the Mindoro Straits where they were under attack by Japanese planes for five days. During this time Bobo witnessed a kamikaze crashing into the USS Ommaney Bay (CVE-79). He participated in combat missions at Lingayen Gulf, Iwo Jima and Okinawa. He recalls the night their ship was in …
