 +  *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 is totally off, if this happens unexpectedly then call SRF

-  * If it tripped check why it tripped, if it is one the causes in the red boxes pictured belowdo NOT attempt to restart. Contact SRF on call and consult them, the picture itself demonstrates a "Excessive Forward Power" issue, these are common and can be reset without consultation.+{{:task:srf_mass_states.png?}} 
 +  * If the RF has tripped, go to __RF Main__ if you're not there alreadythen click "Details" on the issue cavity as shown below 
 +{{:task:cav_details.png?}}
  
-{{:task:cav_resettable.png?400|}}+  * 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.

-  *__MTCA 06__+  *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!
