Eighteenth year progress report, July 1, 1974--June 31, 1975

Description: Progress is reported for studies on the effects of embryonic x irradiation at doses of 50 or 100 R on the lifespan and incidence of leukemia in adult mice and rats. The effects of three 100 R doses on the first day of gestation on cell death in the embryos were also studied. (CH)

Damages to DNA that result in neoplastic transformation

Description: Some topics discussed are: correlation between carcinogens and mutagens; defective DNA repair in uv-damaged xeroderma pigmentosum cells; analysis of nucleotide damage to DNA following exposure to chemicals or radiations; photoreactivation in uv-irradiated Escherichia coli; tumor development in fish; excision repair as an aid in identifying damage; detection of excision repair; role of endonucleases in repair of uv damage; and alkylation products and tumors.

Radiation-enhanced diffusion in metals and alloys

Description: Some phenomena that involves diffusion during irradiation include fission-product redistribution in reactor fuels, defect clustering in CTR walls or fast-reactor cladding, smearing-out of gradients in ion-implanted semiconductors, and microstructure development in a HVEM. This paper is a review of the basics of radiation-enhanced diffusion (REM). The present status of REM today is somewhat the same as diffusion in the 1940's, and recommendations are made for further work. 105 references. (DLC)

Neutron Soft Errors in Xilinx FPGAs at Lawrence Berkeley National Laboratory

Description: The LBNL 88-Inch Cyclotron offers broad-spectrum neutrons for single event effects testing. We discuss results from this beamline for neutron soft upsets in Xilinx Virtex-4 and -5 field-programmable-gate-array (FPGA) devices.

Standard Practice for Dosimetry of Proton Beams for use in Radiation Effects Testing of Electronics

Description: Representatives of facilities that routinely deliver protons for radiation effect testing are collaborating to establish a set of standard best practices for proton dosimetry. These best practices will be submitted to the ASTM International for adoption.

Defects in metal crystals. Progress report, May 1, 1973--April 30, 1974

Description: Progress was made in the following areas: FIM (field ion microscopy) studies of defects in W irradiated with W ions or electrons; FIM studies of Au irradiated with Au or Xe ions; FIM and electrical resistivity study of vacancy defects in quenched W; FIM studies of dilute Pt alloys; measurement of the range of focused replacement sequences in Au; investigation of grain boundary strtucture (using Au); FIM observation of dissociated screw dislocations in Mo; calculation of properties of point defects in metals; and atom probe FIM.
