We present an asynchronous circuit for an arbiter cell that can be used to construct cascaded multiway arbitration circuits. The circuit is completely speed-independent. It has a short response delay at the input request-grant handshake link due to both a) the propagation of requests in parallel with starting arbitration and b) the concurrent resetting of request-grant handshakes in different cascades...
High-power relativistic electron beam focussing represents an important problem to be solved in order to make the controlled pulsed electron fusion feasible. As shown by L. I. Rudakov [1, 2], a relativistic electron beam with a current 107A and a power density. in the beam 1013W/cm2 is required. The “Kalmar-1” accelerator, producing a relativistic electron beam with a 5·1011 – 5·1012W/cm2 power density,...
