We report on the activity of CERN and INFN-LNF groups on the development of large area GEM detectors. The two groups work together within the RD51 Collaboration, to aim at the development of Micro-pattern Gas detectors technologies. The vast request for large area foils by the GEM community has driven a change in the manufacturing procedure by the TS-DEM-PMT laboratory, needed to overcome the previous size limitation of 450 x 450 mm(2). Now a single-mask technology is used allowing foils to be made as large as 450 x 2000 mm(2). The limitation in the short size, due to the definite width of the raw material, can be overcome by splicing more foils together. A 10 x 10 cm(2) GEM detector with the new single-mask foil has been tested with X-rays and the results are shown. Possible future applications for large area GEM are the TOTEM experiment upgrade at CERN, and the KLOE-2 experiment at the Dafne Phi-factory in Frascati. (C) 2009 Elsevier B.V. All rights reserved.

Abstract
We report on the activity of CERN and INFN-LNF groups on the development of large area GEM detectors. The two groups work together within the RD51 Collaboration, to aim at the development of Micro-pattern Gas detectors technologies. The vast request for large area foils by the GEM community has driven a change in the manufacturing procedure by the TS-DEM-PMT laboratory, needed to overcome the previous size limitation of 450 x 450 mm(2). Now a single-mask technology is used allowing foils to be made as large as 450 x 2000 mm(2). The limitation in the short size, due to the definite width of the raw material, can be overcome by splicing more foils together. A 10 x 10 cm(2) GEM detector with the new single-mask foil has been tested with X-rays and the results are shown. Possible future applications for large area GEM are the TOTEM experiment upgrade at CERN, and the KLOE-2 experiment at the Dafne Phi-factory in Frascati. (C) 2009 Elsevier B.V.
