AIDA snout was reconnected and we saw originally a very good reduction in noise from S452 (fig 1) Occasional bursts of increased rates were noticed, perhaps related to works in S4. Tape rate at optimal conditions was around 6 MB/s We still saw some extrinsic noise in waves, two frequencies observed : 1.5 MHz and 100 kHz or so Figs 2, 3 are at 50 MS/s Figs 4, 5 are at 5 MS/s Today the situation has become a lot worse for reasons still unknown. aida01 shows very strong noise, frequency 125 kHz or so it seems (still at 5 MS/s) Amplitude 100 mV or so I think Investigation still underway
