Abstract

Neutron beamlines frequently include moving components such as neutron choppers. These components are typically wheels that rotate about a fixed axis in order to preferentially transmit or absorb neutrons of the desired energies. Capabilities were developed and implemented into MCNPX to include materials and surfaces in motion. In conclusion, the Chopper Extension implements rotating surfaces and media in MCNPX in order to provide a direct way to include rotating components in models for background calculation purposes.

Non-static surfaces in MCNPX: The chopper extension

Conference Grammer, Kyle ; Gallmeier, Franz X. ; Iverson, Erik B.

Rotating objects, such as choppers, are common components of a neutron beamline, and the motion of these components is not described in the static geometry of an MCNPX model. The special case of non-static surfaces for rotation about a stationary point in space has been developed for MCNPX. In addition, velocity dependent kinematics due to the motion of the medium have been implemented. This implementation allows for the simulation of rotating objects at speeds comparable to the velocity of cold neutrons. Applications of the chopper extension will be discussed, including the direct simulation of a bandwidth chopper system, the thermalizationmore »« less

A new high-speed x-ray beam chopper.

Conference McPherson, A ; Wang, J ; Lee, P L ; ...

A new high-speed x-ray beam chopper using laser scanner technology has been developed and tested on the SRI-CAT sector 1 beamline at the Advanced Photon Source (APS) storage ring (1). As illustrated in figure 1, it is compact in size and has two sets of transmission windows: BK-7 glass for visible light transmission and 0.23-mm-thick Be for the transmission of x-rays. The rotor is made of aluminum and has a diameter of 50.8 mm. A 0.5-mm-wide and 2.29-mm-tall slit is cut through the center of the rotor. The circumference of the rotor has a coating of 1-mm-thick Ni, which givesmore »« less

Implementation of a small-angle scattering model in MCNPX for very cold neutron reflector studies

Conference Grammer, Kyle B. ; Gallmeier, Franz X.

Current neutron moderator media do not sufficiently moderate neutrons below the cold neutron regime into the very cold neutron (VCN) regime that is desirable for some physics applications. Nesvizhevsky et al [1] have demonstrated that nanodiamond powder efficiently reflect VCN via small angle scattering. He suggests that these effects could be exploited to boost the neutron output of a VCN moderator. Simulation studies of nanoparticle reflectors are being investigated as part of the development of a VCN source option for the SNS second target station. We are pursuing an expansion of the MCNPX code by implementation of an analytical small-anglemore »« less

CALCULATION OF A FAST NEUTRON CHOPPER SYSTEM

Technical Report Ceulemans, H

From the equations of motion of the neutron, the charaeteristics of neutron transmission through rotating slits are calculated. These characteristics include the form of the transmission probability curve, the width of this curve, and the maximum height. By the use of dimensionless coefficients in formulas and graphs, these factors can be used directly for any chopper design. Attention is also given to the influence of collimators and of beam divengency. The way in which they influence the transmitted spectrum is indicated. Limits for the dnopper parameters are determined in order to satisfy the resolution requirements, and a choice is mademore »« less
Feasibility study into the use of mechanical choppers to alter the natural time structure of the APS

Journal Article Mills, D M - Rev. Sci. Instrum.; (United States)

In standard operating mode, the Advanced Photon Source (APS) is projected to be with 20 equally spaced bunches of positrons separated by 177 ns. This time structure may not be optimal for all experiments, particularly those experiments that require long periods (microseconds to milliseconds) of darkness preceding and/or succeeding the x-ray burst. As a result, an ongoing study is being made into the possibility of altering the natural time structure of the x-ray bursts from the APS. One possibility is through the use of fast kicker magnets (wobblers). A more passive approach is through the use of high-speed mechanical choppers.more »« less
