 h2. Overview 

 The simplest strongly bound quark-gluon systems in nature are the two lightest quark-antiquark quarkantiquark 
 pairs, pions and kaons, and the two lightest three-quark systems, protons and neutrons 
 - these also provide the building blocks for the atomic nuclei at the core of the atom. Gaining a 
 quantitative description of the nature of these systems, including a revealing of their inner 
 structure and an understanding of the dynamics that bind them, is thus of great importance for 
 our understanding of the fundamental structure of matter. This experiment is aimed to confirm 
 the potential of kaon measurements both for studies of the kaon structure itself and of the 3D 
 structure of the proton, in terms of spatial imaging (tomography). In particular, E12-09-011 will 
 probe if the measurements to map the spatial extension of the charged pion can be extended to 
 those of the charged kaon, and if kaons can be utilized to enable 3D spatial tomography of 
 strange quarks. 
 The E12-09-011 experiment is an exclusive measurement of the L/T separated kaon 
 electroproduction cross section important for understanding the role of strangeness in GPD 
 studies and the kaon form factor. It will for the first time make precision measurements of the 
 L/T separated kaon electroproduction cross sections as a function of Q2 
  above the resonance 
 region. These data will provide information about the onset of the Q2 evolution in kaon 
 production. A direct comparison of the scaling properties of the pion + and kaon  separated cross 
 sections would provide an important tool for the study of the onset of factorization in the 
 transition from the hadronic to the partonic regime, and provide a possibility to study effects 
 related to SU(3). The L/T separated cross sections at low –t can further provide constraints of the 
 largely unknown kaon form factor.
