Two compact calorimeters are foreseen, LumiCal and BeamCal. Both are designed as sandwich calorimeters with very thin sensor planes to keep the Molière radius small, facilitating such the measurement of electron showers in the presence of background. Silicon sensor prototypes and dedicated FE ASICs have been developed and produced. In recent beam tests, a multi-plane compact prototype was equipped with thin sensor planes, installed in 1 mm gaps between tungsten plates of one radiation length thickness, and fully assembled with readout electronics. The latest status of the calorimeter prototype development will be presented, including selected performance results, obtained in a 5 GeV electron beam at DESY, and compared the expected performance obtained from simulation. 000490729 536__ $$0G:(DE-HGF)POF4-611$$a611 - Fundamental Particles and Forces (POF4-611)$$cPOF4-611$$fPOF IV$$x0 000490729 693__ $$0EXP:(DE-MLZ)NOSPEC-20140101$$5EXP:(DE-MLZ)NOSPEC-20140101$$eNo specific instrument$$x0 000490729 7001_ $$0P:(DE-HGF)0$$aFCAL Collaboration$$b1$$eCollaboration author 000490729 8564_ $$uhttps://indico.cern.ch/event/1064327/contributions/4893174/ 000490729 8564_ $$uhttps://bib-pubdb1.desy.de/record/490729/files/FCCee_May_2022.pdf$$yRestricted 000490729 8564_ $$uhttps://bib-pubdb1.desy.de/record/490729/files/FCCee_May_2022.pdf?subformat=pdfa$$xpdfa$$yRestricted 000490729 909CO $$ooai:bib-pubdb1.desy.de:490729$$pVDB 000490729 9101_ $$0I:(DE-588b)2008985-5$$6P:(DE-H253)PIP1003723$$aDeutsches Elektronen-Synchrotron$$b0$$kDESY 000490729 9131_ $$0G:(DE-HGF)POF4-611$$1G:(DE-HGF)POF4-610$$2G:(DE-HGF)POF4-600$$3G:(DE-HGF)POF4$$4G:(DE-HGF)POF$$aDE-HGF$$bForschungsbereich Materie$$lMatter and the Universe$$vFundamental Particles and Forces$$x0 000490729 9141_ $$y2022 000490729 9201_ $$0I:(DE-H253)ZEU-EXP_AT-20120731$$kZEU-EXP/AT$$lAstroteilchenphysik$$x0 000490729 980__ $$aconf 000490729 980__ $$aVDB 000490729 980__ $$aI:(DE-H253)ZEU-EXP_AT-20120731 000490729 980__ $$aUNRESTRICTED
