Indeed nothing is predictable. We can only assume things on what is *planed* and *promised*, and you can take my words on the fact that I will do my best to have it done properly and as close to the expectations as possible. But again, nobody can really predict the future. Finger crossed. Cheer

Yes, Tim is right… for now… in few years, with the E-XFEL, we'll get to much less sample, and much more time available. But that's in few years. Leo On Dec 10, 2013, at 10:01 AM, Tim Gruene wrote: > Dear Careina, > > you can also apply for beamtime at PETRA-III. You get away with the same > s

Dear Careina, you can also apply for beamtime at PETRA-III. You get away with the same size crystals but only require a nano liter drop rather than a few ml of your sample. And you probably get beamtime much quicker because all the equipment is installed and collecting a data set takes very short

Dear Jens, Careina this is not really an *advantage*, but rather a *convenience*. You can still use big crystals if you'd like to, but as they usually never survive more than one shot (few femtosec), you'd need a lot of these bigger crystals to collect a full data. And yes, I would also highly

Careina, If your target is interesting enough, try to reproduce the small crystals in batch and apply for FELS time. Small crystals are actually an advantage there. Cheers, Jens On Wed, 2013-12-04 at 21:41 -0800, Careina Edgooms wrote: > Hi all > > > Any advice on how to get bigger crystals

Hi all Any advice on how to get bigger crystals from conditions that give showers of tiny crystals? I am getting small pretty looking individual crystals but they are too small and they don't seem to grow. In fact, in some instances if left for a couple of days they actually dissolve. I have fi
