Non-reactor neutron sources for BNCT (Boron Neutron Capture Therapy)
The focus of this study is the indentification of key feasibility issues for the use of non-reactor neutron sources for Boron Neutron Capture Therapy (BNCT). Of the non-reactor neutron sources surveyed, the /sup 7/Li(p,n) reaction appears to be the most favorable for producing epithermal neutrons for BNCT, and RFQ accelerators are best for producing the desired proton beam. At a proton energy of 2.5 MeV, the total neutron yield is 1.49 /times/ 10/sup /minus/4/ neutrons/proton, with a forward energy spectrum extending up to 780 keV and peaked at 500-600 keV. At I = 20 mA, the total neutron yield wouldmore » -
Compact, inexpensive, epithermal neutron source for BNCT
A new rf-focused linac structure, designed specifically to increase the acceleration efficiency and reduce the cost of linac structures in the few-MeV range, may win the role as the optimum accelerator-based epithermal neutron source for the BNCT application. This new linac structure resembles a drift tube linac (DTL) with radio frequency quadrupole (RFQ) focusing incorporated into each 'drift tube,' hence the name R lowbar f F lowbar ocused D lowbar TL, or RFD. It promises superior acceleration properties, focusing properties, and CW capabilities. We have a proposal under consideration for the development of an epithermal neutron source, based on themore » -
Novel methods for ultra-compact ultra-low-power communications.
This report describes a new algorithm for the joint estimation of carrier phase, symbol timing and data in a Turbo coded phase shift keyed (PSK) digital communications system. Jointly estimating phase, timing and data can give processing gains of several dB over conventional processing, which consists of joint estimation of carrier phase and symbol timing followed by estimation of the Turbo-coded data. The new joint estimator allows delay and phase locked loops (DLL/PLL) to work at lower bit energies where Turbo codes are most useful. Performance results of software simulations and of a field test are given, as are detailsmore »
