abstract = {{At GSI/FAIR heavy, highly charged ions for precision experiments are stripped at high energy and then slowed down in steps and cooled. Final deceleration to about 1 MeV/u is done in a dedicated low-energy storage ring. For this, the existing storage ring CRYRING, has been transferred from Stockholm to Darmstadt, refurbished and taken into operation. The CRYRING@ESR facility is in routine operation now providing ions for experiments either via the ESR but also from a local ECR ion source. Major challenges are the detection of weak and slow ion beams and the vacuum conditions. To get well below 1 MeV/u ion beam energy, a linear decelerator in conjunction with a Penning trap, HITRAP, has been built and partly commissioned. After deceleration to only a few eV/nucleon electron cooling and resistive cooling shall be applied. Electron cooling is relatively unexplored in Penning traps. However, a first interaction of simultaneously stored electrons with highly-charged ions has been detected in the HITRAP cooling trap recently. Further investigation and especially an improved alignment eventually lead to first signs of electron cooling of highly-charged ions in a Penning trap.}},
