Large-scale equipment is costly and implies expensive maintenance. For this reason, its usage must be optimized. Funding agencies have granted such equipment within the multiuser calls, so as to make it available to the whole community needing it. On the other hand, this equipment is today in great part automated, and when referring to routine work, a same technician may monitor several pieces of equipment at the same time. Bearing this in mind, the pieces of equipment must be grouped in a common space to facilitate this practice. It is up to universities and Research Centers to create conditions for those multiuser pieces of equipment to be used collectively and democratically.
