... Added 1 pF capacitor: U13 Pin 3 to ground on all 16 downconverter boards (from MAX4217 op-amp input to ground). ... Added 2.2Kohm size 803 surface mount resistor on back of jumper post SW1: Pin 2 to Pin 3. This is to keep the 16 channel DAC gain control board from occasional oscillation--The DAC chip cannot drive a heavy capacitive load, and there is a bypass cap on the gain control voltage input on the downconverter board. ...

SLIDE 1 Coherent beam­beam e#ects study. ... He has shown that a finite length (in other words equal to # # ) of colliding bunches can lead to the coupling of synchro­betatron modes in the beam­beam system, and thus a head­tail type instability of colliding bunches may arise. ... These modes have been observed in di#erent machines. ... SLIDE 5 Figure shows the dependence of the measured and calculated synchro­betatron mode tunes on the beam current for equal electron and positron bunch intensities. ...
