=====MPS Recovery===== {{tag>needs_review}} ====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:rf_main_overview.png?}} {{: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. {{:task:cav_resettable.png?}} *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! {{:task:mps_operator_rf_reset.png?}} ===MTCA 06=== s ====Diagnosing==== ====Other Issues==== ===== Links/Media ===== * [[https://portal.frib.msu.edu/sites/accsystems/preoperation/_layouts/15/WopiFrame2.aspx?sourcedoc=%7bEEE947E8-4FAA-47DB-BBAB-4FAE59CD87ED%7d|SRF call list]] ---- Shane: hellooooo :3 >Shane: dont do that X(
