Low energy regime of nuclear physics can provide a tremendous insight into the realm of subatomic and particle physics. Precision mass measurements of short-lived isotopes is one such endeavor that can probe unitarity of the CKM matrix and CVC hypothesis, understand nucleosynthesis path, nuclear structure, help improve nuclear mass models and so on. TITAN at TRIUMF is a facility where precision mass measurement of short-lived isotopes is carried out. The unique feature of TITAN is the combination of three online ion traps that enables mass measurement of short-lived isotopes with very high precision. Presently an EBIT increases the charge state to improve the precision. However, the breeding process causes large energy spread. Accuracy of measured mass is linearly dependent on charge state while the increased emittance of beam has a negative impact on trapping efficiency and hence on precision. To overcome the drawback due to energy spread, a cooler Penning trap being developed. The trap is designed to use charged particles to reduce the beam emittance by sympathetic cooling and currently undergoing off-line tests. Working principles and updates on the status will be presented.
