In this poster, we will describe the key developments made in our setup to switch from a clock using fermionic isotopes of mercury to bosonic isotopes of mercury. Initially, we must establish the magnetic field necessary for the quenching method, i.e. to induce the bosonic clock transition. We have introduced a technique to create a strong magnetic field during the probing time. Furthermore, we have enhanced our control over the magnetic environment. Secondly, as we aim to observe the clock transition, we have had to enhance the capabilities of our ultrastable light generation. This enhancement was crucial to provide a tuning range sufficient to reach the frequency of any of the five stable bosonic isotopes while maintaining spectral quality. Thirdly, we calculated the theoretical Rabi pulsation for a clock utilizing bosonic isotopes, determining that we must increase the the probe laser power to achieve a sufficiently large Rabi pulsation. This adjustment is necessary to facilitate the initial exploration of the transition.
