    keyword=low pressure and HP heater

    Both times when there was a significant drop in pressure and temperature, it appears that there was a slight temperature increase before the beam trip. The HP heater power went to low. However, since the plot stopped at scale of 200, I can not tell if it bottomed out. So I told Bob to inform TO to have the proper scale set when log the stripe chart. If it was bottomed out, then we will need to increase coolant flow to prevent this kind of problem to happen again.
