I seriously Murphy Law really exist sia. Yesterday, someone's mechanical pump in the lab end up in smokes and trip the electrical power supply in the lab.. so end up, my equipment cyro pump needs to be regen (a process that takes 1 day to complete) hence I used the other pump in my system (turbo pump) and guess what, I went off to do some work and come back..... the turbo pump has crash.. apparently another power trip... So all my lab's cyro pump is down !!!! and must be immediately regen... if not one pump coat ~$70k will just go down the drain !!! imagine four of them down !!! And luckily my turbo pump survive the crash... turbo pump cost $50k !!! faintz.... But luckily yest wait till nite time then still manage to do the experiment with the turbo pump. BUT !!! today took out the sample.... FAILED product.. argh........ now got to redo again the 8 hrs process... Siong ah !!!!
