Re: TouschekLifetime: machine vs model

I am getting better with the comparison model / machine, having introduced random + multipole errors, corrected orbit, coupling etc
I am off by 20 to 30 % at different RF voltages. I still need to create a calibrated model though.

Having said that I have realized that when I measure the LT in the machine I wait to stabilize the system, which basically means I am letting polarization to set up, at least partially. On the other hand I understand that touschekLifetime code does not include polarization.
Do you adopt any strategy at APS in order to get a reliable/stable LT and avoid polarization to build up? Is there any plane to include P in the touschekLifetime code?

Thanks anyway

Marco,

There's no plan to add polarization, but it would be a good addition. We'll try to get it into the next release.
