Advancing the Fundamental Understanding of Fission: 2014 LDRD 20120077DR Review
The following slides were presented as part of the LDRD 20120077DR Progress Appraisal Review held Tuesday, February 4, 2014. This is part of an ongoing project assessment the previous of which was documented in LA-UR-13-21182. This presentation documents the progress made against the goals agreed to as part of the 2013 review.

Characterization of the ionization chamber for the SPIDER detector
We request 3 days of ATLAS beams for testing the ionization chamber component of the SPIDER detector, a spectrometer for mea suring the mass yields of neutron-induced fission fragments. The ion ization chamber will be a stand alone detector to be coupled to the end of the beam pipe at zero degrees. These tests are a mass and energy specific characterization of the ionization chamber operating conditions specific to SPIDER, including entrance window material options. Once tested, the results will be applied to the energy cal ibration process of SPIDER, a crucial step to achieving high mass resolution.

A high resolutuion ionization chamber for the SPIDER fission fragment detector
An ionization chamber for measuring the energy loss and kinetic energy of fragments produced through neutron-induced fission at the Los Alamos Neutron Science Center (LANSCE) has been designed as a component of the the new SPIDER detector. Design criteria included energy resolutions of <1% for high energy resolution and increased charge resolution. The ionization chamber will be combined with a high resolution time-of-flight detector to achieve fragment yield measurements with mass and nuclear charge resolutions of 1 amu and Z=1. The present status of the ionization chamber will be presented.

TPC measurement support
A new instrument for high precision fission cross sections, the Time Projection Chamber (TPC), is being developed by the NIFFTE (Neutron Induced Fission Fragment Tracking Experiment) collaboration which consists of six universities and three national laboratories. The measurements with the TPC will be carried out at the Los Alamos Neutron Science Center (LANSCE), and one of the roles of the LANL collaborators is to support the TPC measurement program. That support for FY12 is outlined in this report.
