Microcomputer control of radiochemical processes
(Elsevier, 1985-11)
A system for control of radiochemical processes has been designed and constructed. Control passes through a single 8-bit port (6522 VIA) to up to 64 on-off sensors and 64 on-off switches. The outputs are latched; they are ...
Implications of a Higgs interpretation of the [zeta](8.3)
(Elsevier, 1985)
We consider the implications if the new state seen by the Crystal Ball collaboration in radiative [Upsilon]-decay, the [zeta](8.3), is interpreted as a Higgs boson. We show that BR([zeta]-->gg)<0.06 or [zeta](8.3) ...
A captive solvent method for rapid radiosynthesis: Application to the synthesis of [1-11C]palmitic acid
(Elsevier, 1985-08)
A method is described for the synthesis of [1-11C]palmitic acid,in which 11CO2 is reacted with a Grignard reagent trapped within the pores of microporous polypropylene powder in a column. The free acid is liberated by ...
Bidirectional light-scattering image processing method for high-concentration jet sprays
(Elsevier, 1985-01)
In order to study the distributions of droplet size and volume density in high-concentration jet sprays, a new technique is developed, which combines the forward and backward light scattering method and an image processing ...
The IMB photomultiplier test facility
(Elsevier, 1985-09-15)
An automatic system for testing up to 32 photomultiplier tubes (PMs) simultaneously under single photon counting conditions has been used to measure characteristics of more than 2500 PMs for use in the Irvine-Michigan-Brookhaven ...
Plasma dynamics in the night-time F-region at Arecibo
(Elsevier, 1985)
Incoherent scatter radar observations of the night-time F-layer at Arecibo, Puerto Rico, are used to determine horizontal gradients in peak electron density and the F-layer height. At certain times of night, in both the ...
The kinetics of cluster fragmentation and depolymerisation
(IOP Publishing Ltd, 1985-10-21)
The equation that describes fragmentation kinetics, such as that which occurs in cluster breakup and polymer chain degradation (depolymerisation), is solved for models where the rate of breakup depends upon the size of the ...
New quantum oscillations in current driven small junctions
(Elsevier, 1985-04-08)
We propose a framework of a quantum mechanical description of current driven tunnel junctions. Based on this description we predict several new effects. These effects can be observed for kBT ET e2/C, where for a normal ...
Design of an enhanced 1 GeV electron neutrino beam
(Elsevier, 1985-05-15)
An enhanced [nu]e beam would be useful for experiments that have been proposed to investigate the time evolution of a [nu]e beam or to test the universality of [nu]e and [nu][mu] interactions. We have performed detailed ...
