Progress Toward the Crosstie Memory VI

This is the sixth annual technical report of progress toward the crosstie memory and it emphasizes work done during the past year. The five previous reports can be obtained upon request of the authors. Progress has proceeded to the point where shift registers can be demonstrated under observation with Bitter solution. Propagation experiments at NSWC were successful along the entire length of the shift register except where the bit enters the detector. Efforts being made to optimize operation are detailed in this report. With the use of Bitter solution a 12 megabit/sec shift rate was demonstrated. Detection at a 1 megabit/sec rate has been demonstrated at Univac. The next step is to demonstrate data in and data out at a high rate.
