Yahoo! We just succeeded putting in our first colliding beam store since the long shutdown ended! The initial luminosity was only ~20% of the norm before the shutdown, but the proton and antiproton intensities were intentionally low. All of the accelerators still need more tune-up work, but delivering the first collisions after a shutdown is a big stepping stone. The experiments need colliding beams to shake out their detectors, too.
While this first store spins, we can catch our breath, get a good night’s sleep (I hope), and prepare for the additional tune-up work.
