====Common Issues====
===Cavity Wobbles and Trips===
  *First we need to check if the cavity has actually tripped. Consult either the [[pages:srf_mass|SRF Page]] or the [[pages:rf_main|RF Main Page]]. Below are 4 examples of possible states for each cavity:
  - This one is totally off, if this happens unexpectedly then call SRF
  - This one just has the RF tripped off, we'll talk more about this one in a bit
  - This one is a wobbled cavity, skip ahead to "Wobbles cont."
  - This is a perfectly on and functioning cavity

{{:task:srf_mass_states.png?}}
  * If the RF has tripped, go to __RF Main__ if you're not there already, then click "Details" on the issue cavity as shown below
{{:task:cav_details.png?}}

  * Now consult the following image to see if the issue with the cavity can be reset without consulting SRF, the image shows a situation where we've tripped on "Excessive Forward Power", very common. Because it's not in a red box we can continue on, if instead we had tripped on "Excessive Cavity Field" for example, we should contact SRF.

  *If it's a resettable issue, follow the following image
{{:task:cav_details.jpg?}}

  *On occasion, the cavity will quickly trip again, if you click details and find that it tripped on "Cavity Field Low" then it's a common issue. Some cavities throw off a lot of X-Rays that can interfere with the abilities of neighboring cavities to ramp up. Here's what to do:
  -First reset the problem cavity
  -Press "Disable" (next to the "Start" button we used earlier) on both of the cavities above and below the problem cavity
  -Click "Start" for all three of them quickly 
  *if this happens again, then include an additional cavity above and below for a total of 5, it really shouldn't ever extend outside of the cryomodule, but cavities like D1372 often require turning off and on all of the cavities in the cryomodule.
  *__Wobbles Cont.__: Welcome back! For instances where the cavity merely wobbled, you can reset them from [[pages:rf_main|RF Main Page]] or [[pages:mps_op|MPS Operator Page]] as shown in the pictures below, then you should be good to send beam again!
