Proceedings of the Sixth Meeting of the International Collaboration on Advanced Neutron Sources

Description: Representatives of the Laboratories of the International Collaboration on Advanced Neutron Sources gathered between 28 June and 2 July, 1982 at Argonne National Laboratory for their sixth meeting, ICANS-VI. The meeting was the first opportunity for participants to see Argonne's Intense Pulsed Neutron Source, which went into full operation in August, 1981, and in an important sense celebrated the coming-on-line of this most recent entry into the world's complement of the new generation of neutro… more

Description: An accelerator group was established at ANL by the request of KFA-Juelich to carry out a conceptual design study and cost estimate for a rapid-cycling synchrotron as a possible first stage program on spallation neutron sources at KFA-Juelich. This set of notes is the individual notes which form the basis of the final report under this proposal prepared in January 1983. This document contains 37 papers/notes for Advanced Accelerator Development - Neutron Source Series Notes...numbered AAD-N-1 th… more

Plastic box: a 4. pi. detector for intermediate energy heavy ion physics

Description: A 4..pi.. array of plastic scintillator has been constructed and used in conjunction with high resolution solid state detectors. The array is employed principally to discriminate multinucleon transfer reactions from three-body (or more) final states. It should be useful for a broad class of experiments in which a global charged particle anticoincidence is required.

Non-reactor neutron irradiation facility: the Argonne Intense Pulsed Neutron Source

Description: A new generation of neutron sources is just coming into existence with great promise for the future. These sources are based on neutron production by spallation from the interaction of high energy protons with a heavy metal target. Currently the highest flux facility of this type is the Intense Pulsed Neutron Source at Argonne National Laboratory. This machine is also unique in its dedication to both slow-neutron scattering and fast-neutron damage studies.

Status report on the WNR/PSR pulsed spallation neutron source at the Los Alamos National Laboratory

Description: Much progress has been made in WNR/PSR facility development and in planning and implementing a full research program since the last ICANS meeting. Construction of the PSR continues on schedule, a significant neutron scattering research program is under way at the WNR that can continue through the construction period, and a formal neutron scattering user program was begun this year. The problem of bothersome backgrounds at the WNR has been solved, and a versatile and effective target-moderator d… more

He-jet system to study short-lived fission-product nuclei at LAMPF

Description: Experiments have been performed at LAMPF which demonstrate the feasibility of utilizing a He-jet system to transport fission products to an on-line mass separator from a target chamber mounted in the 800-MeV, >600..mu..A main proton beam. Activities of essentially all elements produced are transported with about 60% absolute efficiency, both for fission reactions and spallation reactions. Transport times are short enough to allow study of activities with half-lives as short as 300 ms. Technical… more

Accelerator breeders: will they replace liquid metal fast breeders

Description: Investigation of accelerator breeders at Brookhaven National Laboratory indicate that the AB-LWR fuel cycle is economically competitive with the LMFBR fuel cycle. The same can be said about the accelerator breeder-High Temperature Gas Reactor symbiosis. This system appears to be very competitive with the added real advantage of superior safety and proliferation resistance. This discussion would be incomplete if the real competitor to accelerator breeding was not mentioned, namely Fusion Hybrid … more

Intense pulsed neutron source accelerator status

Description: The Intense Pulsed Neutron Source (IPNS) facility has been in operation since November 1, 1981. From that date through August 1, 1983, the accelerator system was scheduled for 7191 hours of operation. During this period, 627 million pulses totaling about 1.1 x 10/sup 21/ protons were delivered to the spallation target. The accelerator has exceeded goals set in 1981 by averaging 8.65 ..mu..A over this two year period. This average beam current, while modest by the standards of proposed machines,… more

ASPUN, Argonne Super Intense Pulsed Spallation Neutron source

Description: Argonne has been in the process of developing plans for pulsed spallation neutron source facilities that would extend the flux levels by at least an order or magnitude over fluxes provided by facilities that are either now in operation or in construction. The ANL facility is called ASPUN for Argonne Super Intense Pulsed Spallation Neutron Source. The heart of ASPUN is a Fixed-Field Alternating Gradient (FFAG) proton synchrotron which, in our opinion, has great potential as a driver for a spalla… more

Spallation and 14-MeV neutron irradiation of stabilized NbTi superconductors

Description: The results on 5 K irradiation available so far may be summarized as follows. (1) Increases of j/sub c/ following neutron irradiation occur only in conductors which are far from the optimal metallurgical treatments. (2) The changes of j/sub c/ following neutron irradiation and a thermal cycle to room temperature are small and in most cases comparable to the results obtained after 77 K irradiation. (3) The data available so far indicate that the degradation of j/sub c/ at 8 T is larger by about … more

ASPUN: design for an Argonne super-intense pulsed neutron source

Description: Argonne pioneered the pulsed spallation neutron source with the ZING-P and IPNS-I concepts. IPNS-I is now a reliable and actively used source for pulsed spallation neutrons. The accelerator is a 500-MeV, 8 to 9 ..mu..a, 30-Hz rapid-cycling proton synchrotron. Other proton spallation sources are now in operation or in construction. These include KENS-I at the National Laboratory for High Energy Physics in Japan, the WNR/PSR at Los Alamos National Laboratory in the USA, and the SNS at the Rutherf… more

Conceptual design of a 1. 1-GeV 500-. mu. A fast-cycling proton synchrotron

Description: A very high intensity proton synchrotron system which could be used for a pulsed spallation neutron source and low energy neutrino and meson physics facility is designed. The synchrotron would accelerate 200 MeV protons to 1.1 GeV with a repetition rate of 50 pulses per sec. The number of protons per pulse is 6.3 x 10/sup 13/, resulting in an average proton current of 500 ..mu..A. In order to accommodate the high intensity considerable attention was directed toward minimizing beam loss, control… more

Spallator: a new option for nuclear power

Description: The principles of the spallator reactor are reviewed. Advances in linear accelerator technology allow the design and construction of high current (hundreds of mA) continuous wave high energy (thousands of MeV) proton machines in the near term. Spallation neutronic calculations building on existing experimental results, indicate substantial neutron yields on uranium targets. Spallator target assembly designs based on water cooled reactor technology indicate operable efficient systems. Fuel cycle… more
